Michael Jones 191c0b87b1 cmd_mac: fix help for 'mac read'
In the only implementation of 'mac read', it doesn't display the
contents of the eeprom as the help indicated unless compiled with
DEBUG. It only re-reads the contents of the EEPROM into memory.
Displaying the contents of the EEPROM is done by passing no
arguments to 'mac'.
