drm/xe: fix mcr semaphore locking for MTL

Browse source

in commit 81593af6c8 ("drm/xe: Convert xe_mmio_wait32 to us so we can
stop using wait_for_us.") the mcr semaphore register read was
accidentally switched from waiting for the register to go to 1 to
waiting for the register to go to 0, so we need to flip it back.
