The prototype of rseq_handle_notify_resume() and rseq_signal_deliver()
had to be changed to fix handling of traps occuring on signal delivery.
The API change was merged at the same time as the rseq MIPS port.
Adapt the MIPS port to this API change.
Fixes: 784e0300fe ("rseq: Avoid infinite recursion when delivering SIGSEGV")
