[PATCH v1 1/1] drm/xe/guc: Do not assert CTB state while sending MMIO

[Tomasz Lis <tomasz.lis@intel.com>]

During VF post-migration recovery, MMIO communication channel to GuC
is used, despite CTB channel being enabled. This behavior is rooted
in the save-restore architecture specification.

Therefore, a VF driver cannot assert that CTB is disabled while sending
MMIO messages to GuC. Such assertion needs to be PF only, or be removed.

This patch simply removes the assertion.
