util/nvmutil: print mac before setting

Browse Source 
this way, if a user does e.g.

./nvm gbe.bin bullshit

It will say: bullshit

Right now, it just says invalid length. This
means if the user wanted to type e.g.

./nvm gbe.bin copy 0

but they typed:

./nvm gbe.bin coyp 0

Now it will tell them that it's trying
to set the MAC address "coyp".

This is because if an invalid command is given,
it's treated as a MAC address instead. This is
by design, to allow e.g.

./nvm gbe.bin xx:1x:1x:xx:xx:xx
