cmd_usage(): simplify return code handling
Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too. Signed-off-by: Wolfgang Denk <wd@denx.de>
