openrisc: Fix up audit_syscall_[entry|exit]() usage
Commits d7e7528bcd456f5c36ad4a202ccfb43c5aa98bc4 and b05d8447e7821695bc2fa3359431f7a664232743 simplified the usage of the audit_syscall_[entry|exit] functions. Unfortunately, the OpenRISC architecture didn't get fixed up along with the other architectures when those patches were pushed. This makes the relevant changes to this architecture.
