Commit [87400e] Maximize Restore History

Fix up more fallout form alpha signal cleanups

Commit c52c2ddc1dfa ("alpha: switch osf_sigprocmask() to use of
sigprocmask()") had several problems. The more obvious compile issues
got fixed in commit 0f44fbd297e1 ("alpha: fix compile problem in
arch/alpha/kernel/signal.c"), but it also caused a regression.

Since _BLOCKABLE is already the set of signals that can be blocked, the
code should do "newmask & _BLOCKABLE" rather than inverting _BLOCKABLE
before masking.
