MIPS: ptrace: Fix regs_return_value for kernel context
commit 74f1077b5b783e7bf4fa3007cefdc8dbd6c07518 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: d7e7528bcd45 ("Audit: push audit success and retcode into arch ptrace.h")
