signals: kill the obsolete sigdelset() and recalc_sigpending() in allow_signal()
allow_signal() does sigdelset(current->blocked) due to historic reason,
previously it could be called by a daemonize()'ed kthread, and
daemonize() played with current->blocked.
Now that daemonize() has gone away we can remove sigdelset() and
recalc_sigpending(). If a user really wants to unblock a signal, it
must use sigprocmask() or set_current_block() explicitely.
