[PATCH v2 4/8] x86/msr: Consolidate rdmsrq() implementations

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

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

Consolidate the two rdmsrq() implementations down to one.

The paravirt.h implementation was probably better, but just stick
with the native one here for consistency.
