[PATCH] Fix for "powerpc/64: use interrupt restart table to speed up return from interrupt" SOFTE loading

This patch loads SOFTE(r1) with lbz, which existing code stores to with
std. This causes interrupt flag corruption on big endian (as Michael
pointed out to me, lbz happens to grab the correct byte on LE kernels
which explains why I didn't run into it).

64e still seems to have an issue I'm chasing, and I still need to send a
fix for the cpu hotplug lock warning.
