powerpc/sstep: Fix array out of bound warning
Compiling kernel with -Warray-bounds throws below warning:
In function 'emulate_vsx_store':
warning: array subscript is above array bounds [-Warray-bounds]
buf.d[2] = byterev_8(reg->d[1]);
~~~~~^~~
buf.d[3] = byterev_8(reg->d[0]);
~~~~~^~~
Fix it by using temporary array variable 'union vsx_reg buf32[]' in
that code block. Also, with element_size = 32, 'union vsx_reg *reg'
is an array of size 2. So, use 'reg' as an array instead of pointer
in the same code block.
