Subject: [RFC 3/4] sparc: remove __GFP_NOFAIL reuquirement

mdesc_kmalloc is currently requiring __GFP_NOFAIL allocation although it
seems that the allocation failure is handled by all callers (via
mdesc_alloc). __GFP_NOFAIL is a strong liability for the memory
allocator and so the users are discouraged to use the flag unless the
allocation failure is really a nogo. Drop the flag here as this doesn't
seem to be the case.
