boot: fix bootdev_list()
uclass_get_device_by_name() is meant to return 0 or a negative error code.
simple_itoa() cannot handle negative numbers.
This leads to output like:
=> bootdev list -p
Seq Probed Status Uclass Name
--- ------ ------ -------- ------------------
c [ ] 18446744073709551614 spi_flash spi.bin@0.bootdev
Convert the status to a positive number. Now we get
Seq Probed Status Uclass Name
--- ------ ------ -------- ------------------
c [ ] 2 spi_flash spi.bin@0.bootdev
