[Xen-devel] [PATCH 13/15] libxl: Constify libxl_device_* param of *_getinfo



The libxl_device_TYPE parameter of all the libxl_device_TYPE_getinfo
function seems to be only used as input to find more information to bi
stored in the libxl_TYPEinfo parameter.

Make sure this is always true and constify the input parameter to avoid
further mistake.
