cmd: sata: fix init command return value

Since commit aa6ab905b2, sata_initialize returns -1 if init_sata or
scan_sata fails. But this return value becomes the do_sata return
value which is equivalent to CMD_RET_USAGE.

In case one issues 'sata init' and that the hardware fails to
initialize, there's no need to display the command usage. Instead
the command shoud just return the CMD_RET_FAILURE value.

Fixes: aa6ab905b2 (sata: fix sata command can not being executed bug)
