ocfs2: switch osb->disable_recovery to enum

Browse source 
commit c0fb83088f upstream.

Patch series "ocfs2: Fix deadlocks in quota recovery", v3.

This implements another approach to fixing quota recovery deadlocks.  We
avoid grabbing sb->s_umount semaphore from ocfs2_finish_quota_recovery()
and instead stop quota recovery early in ocfs2_dismount_volume().


This patch (of 3):

We will need more recovery states than just pure enable / disable to fix
deadlocks with quota recovery.  Switch osb->disable_recovery to enum.
