qxl: fix qxl_set_dirty call in qxl_dirty_one_surface

Browse source 
qxl_set_dirty() expects start and end as range specification.
qxl_dirty_one_surface passes 'size' instead of 'offset + size' as end
parameter.  Fix that.  Also use uint64_t everywhere while being at it.

Bug was added by "e25139b qxl: set only off-screen surfaces dirty instead
of the whole vram" and carried forward unnoticed by "5cdc402 qxl: fix
surface migration".
