LU-16772 quota: protect lqe_glbl_data in qmt_site_recalc_cb
lqe_glbl_data should be protected with lqe_glbl_data_lock in
qmt_site_recalc_sb like it did in other places. Otherwise it
may cause following panic:
BUG: unable to handle kernel NULL pointer at
00000000000000f8
qmt_site_recalc_cb+0x2f8/0x790 [lquota]
cfs_hash_for_each_tight+0x121/0x310 [libcfs]
qmt_pool_recalc+0x372/0x9f0 [lquota]
Also protect lqe_glbl_data access with lqe_glbl_data_lock in
qmt_lvbo_free().
