e1000: remove dead e1000_init_eeprom_params calls
The device probe method e1000_probe calls e1000_init_eeprom_params
itself so there's no reason to call it again from e1000_do_write_eeprom
or e1000_do_read_eeprom.
The sentence above assumes that e1000_init_eeprom_params is effective.
e1000_init_eeprom_params depends mostly on hw->mac_type and e1000_probe
bails out early if it can't set mac_type (see e1000_init_hw_struct, then
e1000_set_mac_type), qed.
Btw, if effective, the removed paths would had been deadlock prone when
e1000_eeprom_spi was set:
-> e1000_write_eeprom (takes e1000_eeprom_lock)
-> e1000_do_write_eeprom
-> e1000_init_eeprom_params
-> e1000_read_eeprom (takes e1000_eeprom_lock)
(same narrative with e1000_read_eeprom -> e1000_do_read_eeprom etc.)
As a final note, the candidate deadlock above can't happen in e1000_probe
due to the way eeprom->word_size is set / tested.
