description:
Adapt prototypes and usage of rdmsr_locked() and wrmsr_locked() to
their implementation.  Both functions don't take the passcode as
argument.

As wrmsr_locked() no longer writes the passcode to the msr the
erratum 721 on my Opteron 2356 really gets patched and cc1 no longer
crashes with SIGSEGV.
