rS329023: Use vm_page_unwire_noq() instead of directly modifying page wire counts.
Summary

The use of atomic_subtract_rel_int() in the riscv and arm64 pmaps seems
to be bogus: it was copied from amd64 (see r321847), and occurs *after* the
pmap_invalidate_page() call that the comment is referring to.
