Christophe Leroy 0b736881c8 powerpc/traps: unrecoverable_exception() is not an interrupt handler 
unrecoverable_exception() is called from interrupt handlers or
after an interrupt handler has failed.

Make it a standard function to avoid doubling the actions
performed on interrupt entry (e.g.: user time accounting).

Fixes: 3a96570ffceb ("powerpc: convert interrupt handlers to use wrappers")
