transport: rewrite command 'transport select' as COMMAND_HANDLER
The mixed use of jim commands and OpenOCD commands is error prone
due to handling of errors through JIM_xx and ERROR_yy.
Rewrite the jim command 'transport select' as OpenOCD command.
This fixes and incorrect check for the return value of function
transport_select(); it returns ERROR_yy but the check is on JIM_xx.
While there, fix the coding style.
