Darrick J. Wong 54e9b09e15 xfs: fix brainos in the refcount scrubber's rmap fragment processor 
Fix some serious WTF in the reference count scrubber's rmap fragment
processing.  The code comment says that this loop is supposed to move
all fragment records starting at or before bno onto the worklist, but
there's no obvious reason why nr (the number of items added) should
increment starting from 1, and breaking the loop when we've added the
target number seems dubious since we could have more rmap fragments that
should have been added to the worklist.

This seems to manifest in xfs/411 when adding one to the refcount field.

Fixes: dbde19da96 ("xfs: cross-reference the rmapbt data with the refcountbt")
