sparc64: Fix rwsem constant bug leading to hangs.
As noticed by Linus, it is critical that some of the
rwsem constants be signed. Yet, hex constants are
unsigned unless explicitly casted or negated.
The most critical one is RWSEM_WAITING_BIAS.
This bug was exacerbated by commit
424acaaeb3a3932d64a9b4bd59df6cf72c22d8f3 ("rwsem: wake queued readers
when writer blocks on active read lock")
