[PATCH v2 09/11] ext4: iloc.bh cleanup in add_new_gdb()

[Vasily Averin]

iloc.bh was taken in ext4_reserve_inode_write() and released
in ext4_mark_iloc_dirty(). It should not be released 2nd time
in rollback after failed ext4_handle_dirty_metadata(gdb_bh)

Fixes b40971426a83 ("ext4: add error checking to calls to ...") # 2.6.38
