drm/vkms: Suppress context imbalance detected by sparse warning

Browse Source 
The functions `vkms_crtc_atomic_begin` and `vkms_crtc_atomic_flush` are
responsible for locking and unlocking a mutex, respectively. Add the
`__acquires` and `__releases` annotations to these functions to prevent
the associated sparse warning about context imbalance.
