x86/paravirt: Fix a !PARAVIRT build warning

Fix

  ./include/trace/events/xen.h:28:31: warning: ‘enum paravirt_lazy_mode’ \
    declared inside parameter list will not be visible outside of this definition or declaration

which turns into a build error:

  ./include/trace/events/xen.h:28:50: error: parameter 1 (‘mode’) has incomplete type
     28 |                 TP_PROTO(enum paravirt_lazy_mode mode), \

due to enum paravirt_lazy_mode being visible only under CONFIG_PARAVIRT.
Just pull it up where it is unconditionally visible.
