x86/paravirt: Make BUG_func() usable by non-GPL modules

Browse Source 
Several inlined functions subject to paravirt patching are referencing
BUG_func() after the recent switch to the alternative patching
mechanism.

As those functions can legally be used by non-GPL modules, BUG_func()
must be usable by those modules, too. So use EXPORT_SYMBOL() when
exporting BUG_func().
