brcmfmac: use local iftype avoiding use-after-free of virtual interface A use-after-free was found using KASAN. In brcmf_p2p_del_if() the virtual interface is removed using call to brcmf_remove_interface(). After that the virtual interface instance has been freed and should not be referenced. Solve this by storing the nl80211 iftype in local variable, which is used in a couple of places anyway.
