md/raid5-cache: Annotate pslot with __rcu notation
radix_tree_lookup_slot() and radix_tree_replace_slot() API expect the
slot returned and looked up to be marked with __rcu. Otherwise
sparse warnings are generated:
drivers/md/raid5-cache.c:2939:23: warning: incorrect type in
assignment (different address spaces)
drivers/md/raid5-cache.c:2939:23: expected void **pslot
drivers/md/raid5-cache.c:2939:23: got void [noderef] __rcu **
