rhashtable: allow rht_bucket_var to return NULL.
Rather than returning a pointer to a static nulls, rht_bucket_var() now returns NULL if the bucket doesn't exist. This will make the next patch, which stores a bitlock in the bucket pointer, somewhat cleaner. This change involves introducing __rht_bucket_nested() which is like rht_bucket_nested(), but doesn't provide the static nulls, and changing rht_bucket_nested() to call this and possible provide a static nulls - as is still needed for the non-var case.
