alpha: fix syscall entry in !AUDUT_SYSCALL case



[ Upstream commit f7b2431a6d22f7a91c567708e071dfcd6d66db14 ]

We only want to take the slow path if SYSCALL_TRACE or SYSCALL_AUDIT is
set; on !AUDIT_SYSCALL configs the current tree hits it whenever _any_
thread flag (including NEED_RESCHED, NOTIFY_SIGNAL, etc.) happens to
be set.
