Tiwei Bie ba5a09630e um: Preserve errno within signal handler 
[ Upstream commit f68b2d5a90 ]

We rely on errno to determine whether a syscall has failed, so we
need to ensure that accessing errno is async-signal-safe. Currently,
we preserve the errno in sig_handler_common(), but it doesn't cover
every possible case. Let's do it in hard_handler() instead, which
is the signal handler we actually register.
