[U-Boot] [PATCH v3] bootm: Handle errors consistently

From: Simon Glass sjg@chromium.org
A recent bootm fix left the error path incomplete. If CONFIG_TRACE is set it may still not be a supported command, so cover that with the unsupported subcommand print. Once we handle BOOTM_STATE_OS_GO, we can just move into the error handler itself, no need for a goto there.

Yes I missed your previous change which solved this problem. This patch looks good to me, thanks.
