[PATCH] drm/xe/tests/mocs: Hold XE_FORCEWAKE_ALL for LNCF regs

[Tejas Upadhyay]

LNCF registers report wrong values when XE_FORCEWAKE_GT
only is held. Holding XE_FORCEWAKE_ALL ensures correct
operations on LNCF regs.

Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/1999
Fixes: a6a4ea6d7d37 ("drm/xe: Add mocs kunit")
