[ Upstream commit b01189333ee91c1ae6cd96dfd1e3a3c2e69202f0 ]
Commit fffe9bee14b0 ("gfs2: Delay withdraw from atomic context") switched from gfs2_withdraw() to gfs2_withdraw_delayed() in gfs2_ail_error(), but failed to then check if a delayed withdraw had occurred. Fix that by adding the missing check in __gfs2_ail_flush(), where the spin locks are already dropped and a withdraw is possible.
