In the last error path in rtl_pci_probe(), the cleanup functions are
skipped due to a wrong goto label. Moreover, the successful call to
rtl_init_rfkill() and ieee80211_register_hw() have to be reverted.
Fix this issue by updating the labels and adding the relevant cleanup
functions to the last error path.
