[Greg Kroah-Hartman]

From: Zhang Yi <yi.zhang@xxxxxxxxxx>

commit d0e36a62bd4c60c09acc40e06ba4831a4d0bc75b upstream.

Fix the error path in free_dqentry(), pass out the error number if the
block to free is not correct.

Fixes: 1ccd14b9c271 ("quota: Split off quota tree handling into a separate file")
