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 20c0d2d4 ("[PATCH] i386: pass proper trap numbers to die chain handlers") may be the earliest of similar changes.
