x86: Use correct byte-sized register constraint in __add()
commit 8c91c5325e107ec17e40a59a47c6517387d64eb7 upstream.
Similar to:
2ca052a x86: Use correct byte-sized register constraint in __xchg_op()
... the __add() macro also needs to use a "q" constraint in the
byte-sized case, lest we try to generate an illegal register.
