rtl_wq is allocated at rtl_init_core, so it makes more sense to destroy it
at rtl_deinit_core. In the case of USB, where _rtl_usb_init does not
require anything to be undone, that is fine. But for PCI, rtl_pci_init,
which is called after rtl_init_core, needs to deallocate data, but only if
it has been called.
That means that destroying the workqueue needs to be done whether
rtl_pci_init has been called or not. And since rtl_pci_deinit was doing it,
it has to be moved out of there.
It makes more sense to move it to rtl_deinit_core and have it done in both
cases, USB and PCI.
Since this is a requirement for a followup memory leak fix, mark this as
fixing such memory leak.
