media: stm32: dma2d: 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.
