[PATCH v2] net/9p: trans_xen: add missing MODULE_AUTHOR/DESCRIPTION/LICENSE

[Jesse Chan]

This change resolves a new compile-time warning
when built as a loadable module:

WARNING: modpost: missing MODULE_LICENSE() in net/9p/9pnet_xen.o
see include/linux/module.h for more information

This adds the license as "Dual MIT/GPL", which matches the header of the file.

MODULE_DESCRIPTION and MODULE_AUTHOR are also added.
