usb: usbeth: smsc95xx: remove EEPROM loaded check

[port of Linux kernel commit bcd218be5aeb by Steve Glendinning]

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.
