powerpc: Fix uninitialised variable in VSX alignment code
This fixes an uninitialised variable in the VSX alignment code. It can
cause warnings from GCC (noticed with gcc-4.1.1). Gcc is actually
correct in this instance, and this bug could cause the alignment
interrupt handler to send a SIGSEGV to the process on a legitimate
access.
