[PATCH] pcmcia: remove internal module use count, use module_refcount instead

Remove the internal driver use_count in ds.c, as the reference counting is
done in the module core anyways, and that reference count is available for
cardmgr's usage by a call to module_refcount.  And if !CONFIG_MODULE_UNLOAD,
rmmod is useless anyways, so avoid that call by cardmgr at all.
