drm/xe/multi_queue: Reject PXP usage on multi-queue exec queues

Browse source

HWDRM is currently the only supported PXP type, and it is display
related, so it cannot be combined with multi-queue exec queue groups.
Reject exec queue creation that requests both multi-queue and PXP,
returning -EINVAL.

The secondary queue path already rejects any PXP property, so this
adds the missing check for the multi-queue primary,
which would otherwise allow the combination.

Validated with igt@xe_exec_multi_queue@sanity, which exercises both
the PXP-unsupported (-ENODEV) and PXP-supported (-EINVAL) paths.

v3:
 - Change commit title prefix to drm/xe/multi_queue:.
 - Add Niranjana's Reviewed-by.
v2:
 - Move the multi-queue + PXP check to exec_queue_user_ext_check() to
   bail out early, keyed off the properties bitmask (Niranjana).
