Marcin Nowakowski 1ea4789615 MIPS: ptrace: Fix regs_return_value for kernel context ...

commit 74f1077b5b upstream.

Currently regs_return_value always negates reg[2] if it determines
the syscall has failed, but when called in kernel context this check is
invalid and may result in returning a wrong value.

This fixes errors reported by CONFIG_KPROBES_SANITY_TEST

Fixes: d7e7528bcd ("Audit: push audit success and retcode into arch ptrace.h")
