Wait a little longer for the erase to complete

Sometimes the erase operation would timeout, but the new MAC address was
still written:

$ /usr/sbin/rtl8168-eeprom -s 2:0 -m 00:0d:b9:4f:0f:7d
failed: 1

initializing pci access
building filter
starting bus iteration
found matching device (02:00.0), base_addr=0xf7c00000 (len=0)
Existing/Old MAC address: 00:0d:b9:4f:0f:7d
Saving EEPROM backup to 000DB94F0F7D.backup
Writing new MAC address 00:0d:b9:4f:0f:7d...
timeout during ERASE
Error during EEPROM WRITE, MAC address is corrupt!
