When the rtlwifi card\nprobe fails or is being detached, the ieee80211_hw is deallocated.\nHowever, irq_prepare_bcn_tasklet may still be running or pending,\nleading to use-after-free when the freed ieee80211_hw is accessed\nin _rtl_pci_prepare_bcn_tasklet().\n\nSimilar to irq_tasklet, add tasklet_kill() in rtl_pci_deinit() to\nensure that irq_prepare_bcn_tasklet is properly terminated
