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.
Fixes: a9302e843944 "alpha: Enable system-call auditing support"
