LU-8842 mdc: Make IT_OPEN take lookup bits lock

Commit 8d161d44214f907a9f2d9cf5a79cd2c83de995c3 from
http://review.whamcloud.com/#/c/10205/3 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.
