ocfs2: fix i_mutex locking in ocfs2_splice_to_file()

commit 328eaaba4e41a04c1dc4679d65bea3fee4349d86 upstream.

Rearrange locking of i_mutex on destination and call to
ocfs2_rw_lock() so locks are only held while buffers are copied with
the pipe_to_file() actor, and not while waiting for more data on the
pipe.
