NFC: fix attrs checks in netlink interface
commit 18917d51472fe3b126a3a8f756c6b18085eb8130 upstream.
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.
