x86/speculation: Add <asm/msr-index.h> dependency
commit ea00f301285ea2f07393678cd2b6057878320c9d upstream. Joe Konno reported a compile failure resulting from using an MSR without inclusion of <asm/msr-index.h>, and while the current code builds fine (by accident) this needs fixing for future patches.
