Add workaround annotation for udisks_client_get_block_for_dev()

Add workaround annotation for udisks_client_get_block_for_dev()

The gobject-introspection parser does not know how to properly handle dev_t
arguments (https://bugzilla.gnome.org/show_bug.cgi?id=584517) and treats them
as gint. But as the native API expects a 64 bit integer, you'll get garbage in
the upper word on 32 bit platforms, which cause
UDisks.Block.get_block_for_dev() to never find a match when using through
introspection.
