net/eth.c: Fix env_enetaddr signed overflow
Assigning the output of simple_strtoul(CB:A9:87:65:43:21) to `char', we are
warned as below:
U-Boot 1.2.0 (Aug 30 2007 - 08:27:37)
DRAM: 256 MB
Flash: 32 MB
In: serial
Out: serial
Err: serial
Net: NEC-Candy

Address in SROM is 00:00:4C:80:92:A2

This patch changes env_enetaddr type from `char' to `unsigned char'.
