Description

Quota have a two issues with Dom files.

1. related with LU-16032 osd: move unlink of large objects to separate thread. This patch move a iput outside of qsd_op_adjust. it caused situation when inode blocks freed but quota refreshed in qsd_op_adjust to early and quota don't seen a quota usage update.

2. osd_declare_destroy not balanced with osd_object_delete. osd_declare_destroy had declare a quota modification for the both quota sites - data/metadata. But osd_object_delete have quota updates just for default quota site. it's 'metadata' site for MDT. It caused situation when block usage and edquot flag isn't updated after unlink

Both fails related to the sanity-quota 75 fails.
