[PATCH 3/9] staging: vc04_services: bcm2835-camera: Remove redundant null check

[Umang Jain]

Remove the buf pointer null check in buffer_cb() as it can never be
NULL. buffer_cb() is always called with a valid mmal_buf pointer
(which is NULL checked) from which, struct vb2_mmal_buf buf pointer
is derived, using container_of macro.
