The block layer calling convention is blk_queue_<limit name>.
blk_queue_max_sectors predates this practice, leading to some confusion.
Rename the function to appropriately reflect that its intended use is to
set max_hw_sectors.

Also introduce a temporary wrapper for backwards compability.  This can
be removed after the merge window is closed.

Several config ROM related functions only peek at the ROM cache; mark
their arguments as const pointers.  Ditto fw_device.config_rom and
fw_unit.directory, as the memory behind them is meant to be write-once.

A few stylistic changes to unify some code patterns in the subsystem:

  - The similar queue_delayed_work helpers fw_schedule_bm_work,
    schedule_iso_resource, and sbp2_queue_work now have the same call
    convention.
  - Two conditional calls of schedule_iso_resource are factored into
    another small helper.
  - An sbp2_target_get helper is added as counterpart to
    sbp2_target_put.

Object size of firewire-core is decreased a little bit, object size of
firewire-sbp2 remains unchanged.

The Unit_Characteristics entry of an SBP-2 unit directory is not
mandatory as far as I can tell.  If it is missing, we would probably
fail to log in into the target because firewire-sbp2 would not wait for
status after it sent the login request.

The fix moves the cleanup of tgt->mgt_orb_timeout into a place where it
is executed exactly once before login, rather than 0..n times depending
on the target's config ROM.  With targets with one or more
Unit_Characteristics entries, the result is the same as before.

The inquiry delay does more harm than good in tests on a recent kernel.

Per SBP-2 clause 5.3, a target shall store 8...32 bytes of status
information.  Trailing zeros after the first 8 bytes don't need to be
stored, they are implicit.  Fix the status write handler to clear all
unwritten status data.

  firewire: sbp2: fix freeing of unallocated memory
  firewire: ohci: fix Ricoh R5C832, video reception
  firewire: ohci: fix Agere FW643 and multiple cameras
  firewire: core: fix crash in iso resource management

If a target writes invalid status (typically status of a command that
already timed out), firewire-sbp2 attempts to put away an ORB that
doesn't exist.  https://bugzilla.redhat.com/show_bug.cgi?id=519772
