alpha: fix syscall entry in !AUDUT_SYSCALL case
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" Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
