These fix different bugs when the probe fails. One of them is the addition to a global list, which is not removed during the error path. That list has been removed. Then, some memory leaks are fixed, which require a change in where the workqueue is destroyed. Finally, the firmware completion is waited to prevent its callback from accessing freed data. These were tested against an "emulated" rtl8192se. It was a changed rtl8139 device under qemu with the rtl8192se PCI ID. Memory allocation failures were injected over 4 different places: init_sw_vars, rtl_pci_init, rtl_init_core and ieee80211_register_hw.
