KVM: x86: Fix BUILD_BUG() in __cpuid_entry_get_reg() w/ CONFIG_UBSAN=y
Take the target reg in __cpuid_entry_get_reg() instead of a pointer to a
struct cpuid_reg. When building with -fsanitize=alignment (enabled by
CONFIG_UBSAN=y), some versions of gcc get tripped up on the pointer and
trigger the BUILD_BUG().
