Subject: signals: cleanup the usage of print_fatal_signal()
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Move the callsite of print_fatal_signal() down, under "if
(sig_kernel_coredump(signr))", so we don't need to check signr != SIGKILL.
We are only interested in the sig_kernel_coredump() signals anyway, and due to
the previous changes we almost never can see other fatal signals here except
SIGKILL.
