ext4: clean up s_mb_rb_lock to fix build warnings with C=1
Running sparse (make C=1) on mballoc.c we get the following warning:
fs/ext4/mballoc.c:3194:13: warning: context imbalance in
'ext4_mb_seq_structs_summary_start' - wrong count at exit
This is because __acquires(&EXT4_SB(sb)->s_mb_rb_lock) was called in
ext4_mb_seq_structs_summary_start(), but s_mb_rb_lock was removed in commit
83e80a6e35
("ext4: use buckets for cr 1 block scan instead of rbtree"),
so remove the __acquires to silence the warning.
