KVM: x86/mmu: Use "unsigned int", not "u32", for SPTEs' @access info

KVM: x86/mmu: Use "unsigned int", not "u32", for SPTEs' @access info

Use an "unsigned int" for @access parameters instead of a "u32", mostly
to be consistent throughout KVM, but also because "u32" is misleading.
@access can actually squeeze into a u8, i.e. doesn't need 32 bits, but is
as an "unsigned int" because sp->role.access is an unsigned int.

No functional change intended.
