tftp_handler do eth_halt when TFTP_ERROR, but eth_halt will remove eth
device if it is an usb network. usbeth's private data will be unaccessable
when usb_eth_free_pkt, touch it will trigger data abort.
Next is the console messages:
=> tftp xxx
...
Loading: *
TFTP error: 'open failed: No such file or directory' (1)
Not retrying...
data abort
pc : [<9feb6ba2>] lr : [<9feb6b9f>]
Fix it.
