cmd: mvebu/bubt: Correctly propagate failure during tftp transport
net_loop() returns signed int type and negative value represents error.
tftp_read_file() returns unsigned size_t type and zero value represents
error. Casting signed negative value to unsigned size_t type cause losing
information about error and bubt thinks that no error happened, and
continue erasing SPI-NOR which cause malfunction device.
Fix this issue by correctly propagating failure during tftp transport.
With this change when there is no eth link, bubt does not erase SPI-NOR
anymore.
=> bubt
