fs/ocfs2/dlm: Use GFP_ATOMIC under spin_lock
coccinelle check scripts/coccinelle/locks/call_kern.cocci found that
in fs/ocfs2/dlm/dlmdomain.c an allocation with GFP_KERNEL is done
with locks held:
dlm_query_region_handler
spin_lock(dlm_domain_lock)
dlm_match_regions
kmalloc(GFP_KERNEL)
Change it to GFP_ATOMIC.
