x86/vmx: introduce vmx_find_msr()

Modify vmx_add_msr() to use a variation of insertion sort algorithm:
find a place for the new entry and shift all subsequent elements before
insertion.

The new vmx_find_msr() exploits the fact that MSR list is now sorted
and reuses the existing code for binary search.
