NFC: fix attrs checks in netlink interface nfc_genl_deactivate_target() relies on the NFC_ATTR_TARGET_INDEX attribute being present, but doesn't check whether it is actually provided by the user. Same goes for nfc_genl_fw_download() and NFC_ATTR_FIRMWARE_NAME. This patch adds appropriate checks. Found with syzkaller.
