Defang Bo 68db21094e nfc: Ensure presence of NFC_ATTR_FIRMWARE_NAME attribute in nfc_genl_fw_download()
[ Upstream commit 280e3ebdaf ]

Check that the NFC_ATTR_FIRMWARE_NAME attributes are provided by
the netlink client prior to accessing them.This prevents potential
unhandled NULL pointer dereference exceptions which can be triggered
by malicious user-mode programs, if they omit one or both of these
attributes.

Similar to commit a0323b979f ("nfc: Ensure presence of required attributes in the activate_target handler").

Fixes: 9674da8759 ("NFC: Add firmware upload netlink command")
