Subject: staging: lustre: mdc: Make IT_OPEN take lookup bits lock

From: Patrick Farrell <paf@xxxxxxxx>

commit 26d2bf1e71525f4c0f644820c30d1344633159e2 upstream.

An earlier commit accidentally changed handling of IT_OPEN,
making it take the MDS_INODELOCK_UPDATE bits lock instead of
MDS_INODELOCK_LOOKUP. This does not cause any known bugs.
