ext4: remove unnecessary ext4_get_group_info in ext4_mb_load_buddy
ext4_mb_load_buddy() calls ext4_get_group_info() for setting both "grp" and "e4b->bd_info", but it could do "e4b->bd_info = grp". Reported-by: Andreas Dilger <adilger@whamcloud.com> Signed-off-by: Tao Ma <boyu.mt@taobao.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
