Description

In the Linux kernel, the following vulnerability has been resolved:

xfs: scrub: unlock dquot before early return in quota scrub

xchk_quota_item can return early after calling xchk_fblock_process_error. When that helper returns false, the function returned immediately without dropping dq->q_qlock, which can leave the dquot lock held and risk lock leaks or deadlocks in later quota operations.

Fix this by unlocking dq->q_qlock before the early return.
