drm/msm/submit: Move copy_from_user ahead of locking bos
We cannot switch to using obj->resv for locking without first moving all
the copy_from_user() ahead of submit_lock_objects(). Otherwise in the
mm fault path we aquire mm->mmap_sem before obj lock, but in the submit
path the order is reversed.
