kdb_main: fix help print
The help command was chopping all the usage instructions such that
they were not readable.
Example:
bta [D|R|S|T|C|Z|E|U|I| Backtrace all processes matching state flag
per_cpu <sym> [<bytes>] [<c Display per_cpu variables
Where as it should look like:
bta [D|R|S|T|C|Z|E|U|I|M|A]
Backtrace all processes matching state flag
per_cpu <sym> [<bytes>] [<cpu>]
Display per_cpu variables
All that is needed is to check the how long the cmd_usage is and jump
to the next line when appropriate.
