Jason Andryuk 0cd774e8c2 tools/libxl: Only access legacy altp2m on HVM 
Only access the HVM union b_info->u.hvm on HVM guests.  The union
access is not guarded, so this reads and sets the default even on
non-HVM guests.  Usually this doesn't matter as PV and PVH unions are
smaller and zero-initialized, but the zero default will be re-written as
a -1 boolean.  Generally, it could incorrectly set b_info->altp2m
through aliased data.

Fixes: 0291089f6e ("xen: enable altp2m at create domain domctl")
