smbd: Pull mtime handling into open_file_ntcreate
This is a performance improvement for heavily contended files, in
particular in a cluster. The separate call to get_file_infos makes us
pull the locking.tdb record twice per open. For a contended file this
can be a performance penalty, this gets the # of record accesses for
the open/close cycle down from 3 to 2.
