[U-Boot] [PATCHv2 0/3] Use return value of cmd_usage

cmd_usage returns 1, so its return value can be used as return value.

Some functions ignore the return value of cmd_usage and return a "1" in the next line. These patches change these calls so that the return value of cmd_usage is used as return value.

*** BLURB HERE ***
