[PATCH 5/8] x86/msr: Consolidate {rd,wr}msr[q]_safe() implementations

[Dave Hansen <dave.hansen@linux.intel.com>]

From: Dave Hansen <dave.hansen@linux.intel.com>

These should be very familiar by now. Use the "raw_" indirection
to consolidate the duplicate implementations. Do four at once now
because these are quite straightforward.
