nfc: Ensure presence of NFC_ATTR_FIRMWARE_NAME attribute in nfc_genl_fw_download()
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 a0323b979f81 ("nfc: Ensure presence of required attributes in the activate_target handler").
Fixes: 9674da8759df ("NFC: Add firmware upload netlink command")
