gfs2: Revert 'Fix "truncate in progress" hang'

Now that interrupted truncates are completed in the context of the
process taking the glock, there is no need for the glock state engine to
delegate that task to gfs2_quotad or for quotad to perform those
truncates anymore.  Get rid of the obsolete associated infrastructure.

Reverts commit 813e0c46c9e2 ("GFS2: Fix "truncate in progress" hang").
