[Intel-xe] [PATCH] drm/xe: Remove extra xe_mmio_read32 from xe_mmio_wait32

[Maarten Lankhorst]

Commit 5a2be6ba6ba0 ("drm/xe: Let's return last value read on
xe_mmio_wait32.") mentions that we should return the last value read,
but we never actually return it. This breaks display which depends on
the value being actually returned where needed.
