Avoid intermediate negative numbers when doing calculations with a mix
of signed and unsigned variables where implicit conversions can lead
to unexpected results.

When kernel queue buffer wraps around to 0, we need to check that rptr
won't be overwritten by the new packet.

<title>drm/amdgpu: revert tile table update for oland</title>

<id>4cf97582b46f123a4b7cd88d999f1806c2eb4093</id>
<content type='text'>
Several users have complained that the tile table update broke Oland
support. Despite several attempts to fix it, the root cause is still
unknown at this point and no solution is available. As it is not
acceptable to leave a known regression breaking a major functionality
in the kernel for several releases, let's just reverse this
optimization for now. It can be implemented again later if and only
if the breakage is understood and fixed.

As there were no complaints for Hainan so far, only the Oland part of
the offending commit is reverted. Optimization is preserved on
Hainan, so this commit isn't an actual revert of the original.

This fixes bug #194761:

<content type='text'>
This reverts commit 10e709cb296c98424c03408d23e3addeddcd4088.

The patch doesn't work at all:
1. The CS can still be blocked because of amdgpu_ctx_add_fence().
2. The order of submission isn't correct any more.
3. We could end up using freed up memory because we now drop the
   ctx reference to early.

This needs to be fixed cleanly by doing the context handling after the BO
handling, but this is a larger task just avoid the obvious crashes for now.

The call to kfd_device_by_id can potentially return null, so check that
dev is null and return with -EINVAL to avoid a null pointer dereference.
