[PATCH] powerpc/32: Restore clearing of MSR[RI] in interrupt_exit_kernel_prepare()

[Christophe Leroy]

Commit 13799748b957 ("powerpc/64: use interrupt restart table to speed
up return from interrupt") removed the inconditional clearing of MSR[RI]
when returning from interrupt into kernel. But powerpc/32 doesn't
implement interrupt restart table hence still need MSR[RI] to be
cleared.
