wifi: rtl818x: initialize eeprom_93cx6 struct to zero

Browse source

Commit 7738a7ab9d ("misc: eeprom: eeprom_93cx6: Add quirk for extra
read clock cycle") added extra 'quirk' field to struct eeprom_93cx6.

Many existing users of eeprom_93cx6, including rtl818x drivers, allocate
the structure on the stack without initializing all fields. As a result,
the added quirk field has an undefined value and can randomly cause
reading wrong data from the EEPROM.

Fix by initializing the structures with {}.
