media: imagination: e5010: Drop unneeded v4l2_m2m_get_vq() NULL check

The v4l2_m2m_get_vq() function never returns NULL.

In e5010_s_fmt(), 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 e5010_s_selection(), the function performs an explicit type check, so
the NULL check couldn't have been intended as a type check.

Drop the unneeded return value check.
