drivers/jtag: usb_blaster: make command handlers more strict

If user used wrong argument number for some usb_blaster_* commands
then openocd show just warning message.
This commit makes command handler's behaviour more strict and
openocd treats wrong argument number as an error.

In addition we already have 'help' and 'usage' information in
struct command_registration ublast_command_handlers[],
so we can drop redundancy messages in command handlers.
