arm64/sve: Fix a couple of magic numbers for the Z-reg count 



There are some hand-written instances of "32" to express the number
of SVE Z-registers.

Since this code was written a #define was added for this, so
convert trivial instances of this magic number as appropriate.

No functional change.
