smsc95xx: remove EEPROM loaded check

The eeprom read & write commands currently check the E2P_CMD_LOADED_ bit is
set before allowing any operations.  This prevents any reading or writing
unless a correctly programmed EEPROM is installed.

This patch removes the check, so it is possible to program blank EEPROMS
via ethtool.
