ethtool: eeprom: fix null-deref on genl_info in dump
commit 9d9effca9d7d7cf6341182a7c5cabcbd6fa28063 upstream.
The similar fix as commit 46cdedf2a0fa ("ethtool: pse-pd: fix null-deref on
genl_info in dump") is also needed for ethtool eeprom.
Fixes: c781ff12a2f3 ("ethtool: Allow network drivers to dump arbitrary EEPROM data")
