powerpc: Fix size of st_nlink on 64bit

commit e57f93cc53b7 (powerpc: get rid of nlink_t uses, switch to
explicitly-sized type) changed the size of st_nlink on ppc64 from
a long to a short, resulting in boot failures.

Al, did you CC me on that ? I don't remember seeing it but it could be

Would this affect my (early user mode) boot problems reported yesterday;
