md-cluster: fix rmmod issue when md_cluster convert bitmap to none
update_array_info misses calling module_put when removing cluster bitmap. steps to reproduce: ``` node1 # mdadm -C /dev/md0 -b clustered -e 1.2 -n 2 -l mirror /dev/sda /dev/sdb mdadm: array /dev/md0 started. node1 # lsmod | egrep "dlm|md_|raid1" md_cluster 28672 1 dlm 212992 14 md_cluster configfs 57344 2 dlm raid1 53248 1 md_mod 176128 2 raid1,md_cluster node1 # mdadm -G /dev/md0 -b none node1 # lsmod | egrep "dlm|md_|raid1" md_cluster 28672 1 <== should be zero dlm 212992 9 md_cluster configfs 57344 2 dlm raid1 53248 1 md_mod 176128 2 raid1,md_cluster node1 # mdadm -G /dev/md0 -b clustered node1 # lsmod | egrep "dlm|md_|raid1" md_cluster 28672 2 <== increase dlm 212992 14 md_cluster configfs 57344 2 dlm raid1 53248 1 md_mod 176128 2 raid1,md_cluster node1 # mdadm -G /dev/md0 -b none node1 # mdadm -G /dev/md0 -b clustered node1 # lsmod | egrep "dlm|md_|raid1" md_cluster 28672 3 <== increase dlm 212992 14 md_cluster configfs 57344 2 dlm raid1 53248 1 md_mod 176128 2 raid1,md_cluster ``` Reviewed-by: NeilBrown <neilb@suse.de> Signed-off-by: Zhao Heming <heming.zhao@suse.com> Signed-off-by: Song Liu <songliubraving@fb.com>
