Remove HV_DRV_VERSION, it has no meaning for upstream drivers.

Initially it was supposed to show the "Linux Integration Services"
version, now it is not in sync anymore with the out-of-tree drivers
available from the MSFT website.

The only place where a version string is still required is the KVP
command "IntegrationServicesVersion" which is handled by
tools/hv/hv_kvp_daemon.c. To satisfy such KVP request from the host pass
the current string to the daemon during KVP userland registration.

Set the hid drvdata prior to invoking hid_add_device() as hid_add_device()
expects this state to be set. This bug was introduced in the recent hid
changes that were made in 07d9ab4f0e52cb ("HID: hid-hyperv: Do not use
hid_parse_report() directly").

Upcoming changes will split the semantics of hid_parse_report()
and hid_parse(), so make sure drivers use hid_parse() in probe().

The file  hid-hyperv.c implements a hid compliant mouse driver for use on a
Hyper-V based system. This driver is currently in the staging area and as part
of the effort to move this driver out of staging, I had posted the driver code
for community review a few weeks ago. This current patch addresses all the
review comments I have gotten to date. All the relevant patches have already
been submitted to the staging tree as well.

As per Greg's suggestion, this patch does not get rid of the code from
the staging area. Once the mouse driver lands under the hid directory,
we will cleanup the staging directory.
