Kemeng Shi 245759d987 ext4: correct grp validation in ext4_mb_good_group 
[ Upstream commit a9ce5993a0 ]

Group corruption check will access memory of grp and will trigger kernel
crash if grp is NULL. So do NULL check before corruption check.

Fixes: 5354b2af34 ("ext4: allow ext4_get_group_info() to fail")
