powerpc: Fix usage of 64-bit instruction in 32-bit altivec code

commit e090aa80321b64c3b793f3b047e31ecf1af9538d upstream.

e821ea70f3b4873b50056a1e0f74befed1014c09 introduced a bug by copying
some 64-bit originated code as-is to be used by both 32 and 64-bit
but this code contains a 64-bit ony "cmpdi" instruction.

This changes it to cmpwi, which is fine since VRSAVE can only contains
a 32-bit value anyway.
