[PATCH 6/7] drm/xe: Don't block messages to the GPU scheduler

[Stuart Summers <stuart.summers@intel.com>]

Right now we are using the state of the GPU scheduler
to determine whether we send and receive messages. There
are some states, however, where we might intentionally
pause the scheduler, like a device wedge, and expect that
messages are resumed later once the user has taken the
hardware state and is attempting to reset, like an unbind.

Remove these checks in the XeKMD and let the GPU scheduler
handle state checks internally.
