media: samsung: s5p-g2d: Drop unneeded v4l2_m2m_get_vq() NULL check
The v4l2_m2m_get_vq() function never returns NULL. The check was probably intended to catch invalid format types, but that's not needed as the V4L2 core picks the appropriate VIDIOC_G_FMT ioctl handler based on the format type, so the type can't be incorrect. Drop the unneeded return value check and, as the return value is not used for other purposes and the function has no side effect, the function call as well.
