KVM: selftests: Rework dynamic XFeature helper to take mask, not bit
Take the XFeature mask in __vm_xsave_require_permission() instead of the
bit so that there's no need to define macros for both the bit and the
mask. Asserting that only a single bit is set and retrieving said bit
is easy enough via log2 helpers.
Opportunistically clean up the error message for the
ARCH_REQ_XCOMP_GUEST_PERM sanity check.
