KVM: Trivial: Use standard CR0 flags macros from asm/cpu-features.h
The kernel now has asm/cpu-features.h: use those macros instead of inventing our own. Also spell out definition of CR0_RESEVED_BITS (no code change) and fix typo. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Avi Kivity <avi@qumranet.com>
