Boris Ostrovsky 84aba677f0 x86/microcode: Remove unnecessary paravirt_enabled check
Commit:

  a18a0f6850 ("x86, microcode: Don't initialize microcode code on paravirt")

added a paravirt test in microcode_init(), primarily to avoid making
mc_bp_resume()->load_ucode_ap()->check_loader_disabled_ap() calls
because on 32-bit kernels this callchain ends up using __pa_nodebug()
macro which is invalid for Xen PV guests.

A subsequent commit:

  fbae4ba8c4 ("x86, microcode: Reload microcode on resume")

eliminated this callchain thus making a18a0f6850 unnecessary.
