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

The v4l2_m2m_get_vq() function never returns NULL.

In the set format handlers, 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 handlers, 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.

In other locations the v4l2_m2m_get_vq() function is called with a
hardcoded V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE type, so the NULL check
can't have been an attempt to catch an invalid type there either.

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