media: mediatek: jpeg: Drop unneeded v4l2_m2m_get_vq() NULL check

Browse Source 
The v4l2_m2m_get_vq() function never returns NULL.

In the set format handler, the check may have been intended to catch
invalid format types, but that's not needed as the V4L2 core picks the
appropriate VIDIOC_S_FMT ioctl handler based on the format type, so the
type can't be incorrect.

In the get format handler, the return value is not used for any purpose
other than the NULL check, which was therefore probably intended to
catch invalid format types. That's not needed for the same reason as in
the set format handler.

Drop the unneeded return value checks and, as the function has no side
effect, the unneeded function call as well.
