lib/rhashtable: cleanup fallback check in bucket_table_alloc()

Browse Source 
Upon allocation failure, the current check with the nofail bits is
unnecessary, and further stands in the way of discouraging direct use of
__GFP_NOFAIL.  Remove this and replace with the proper way of determining
if doing a non-blocking allocation for the nested table case.
