KVM VMX changes for 7.1

 - Drop obsolete (largely ignored by hardwre) branch hint prefixes from the
   VMX instruction macros, as saving a byte of code per instruction provides
   more benefits than the (mostly) superfluous prefixes.

 - Use ASM_INPUT_RM() in __vmcs_writel() to coerce clang into using a register
   input when appropriate.

 - Drop unnecessary parentheses in cpu_has_load_cet_ctrl() so as not to suggest
   that "return (x & y);" is KVM's preferred style.
