net: tftpsrv: Get correct client MAC address

Browse source 
NetServerEther was not being cleared in the tftp server code, so the
destination MAC address would be whatever the last destination MAC
address was.

Scenario:
U-Boot:
	dhcp
	tftpsrv
Host:
	Send device WRQ
Device:
	Responds with ACK to dhcp server mac address with
	host ip address

By clearing NetServerEther, we force a lookup of the host MAC address
to go with the associated host IP.
