LU-16887 scrub: delete OI when inode missing

LU-16887 scrub: delete OI when inode missing

osd_iget_check() function have no ability to check
OI when osd_iget() returns error, because inode is
lost during error. Let's return old logic.

Scrub doesn't check consistency between OI and inode
for items from inconsistent list. When OI points to
worng inode, OI record should be deleted.
