Tiezhu Yang 6933c11fb5 LoongArch: Do not kill the task in die() if notify_die() returns NOTIFY_STOP
If notify_die() returns NOTIFY_STOP, honor the return value from the
handler chain invocation in die() and return without killing the task
as, through a debugger, the fault may have been fixed. It makes sense
even if ignoring the event will make the system unstable: by allowing
access through a debugger it has been compromised already anyway. It
makes our port consistent with x86, arm64, riscv and csky.

Commit 20c0d2d440 ("[PATCH] i386: pass proper trap numbers to die
chain handlers") may be the earliest of similar changes.
