e100: fix eeh on pseries during ethtool -t

Olaf Hering reported a problem on pseries with e100 where ethtool -t would
cause a bus error, and the e100 driver would stop working.  Due to the new
load ucode command the cb list must be allocated before calling
e100_init_hw, so remove the call and just let e100_up take care of it.
