MIPS: Fix IRQ tracing when call handle_fpe() and handle_msa_fpe()
[ Upstream commit 31e1b3efa802f97a17628dde280006c4cee4ce5e ]
Register "a1" is unsaved in this function,
when CONFIG_TRACE_IRQFLAGS is enabled,
the TRACE_IRQS_OFF macro will call trace_hardirqs_off(),
and this may change register "a1".
The changed register "a1" as argument will be send
to do_fpe() and do_msa_fpe().
