call_usermodehelper: no need to unblock signals
____call_usermodehelper() correctly calls flush_signal_handlers() to set
SIG_DFL, but sigemptyset(->blocked) and recalc_sigpending() are not
needed.
This kthread was forked by workqueue thread, all signals must be unblocked
and ignored, no pending signal is possible.
