[PATCH] x86/xen: silence smatch warning in pmu_msr_chk_emulated()

[Juergen Gross <jgross@xxxxxxxx>]

Commit 8714f7bcd3c2 ("xen/pv: add fault recovery control to pmu msr
accesses") introduced code resulting in a warning issued by the smatch
static checker, claiming to use an uninitialized variable.

This is a false positive, but work around the warning nevertheless.
