gdbstub: Fix handling of '!' packet with new infra

Since the '!' packet is not handled by the new infrastructure,
gdb_handle_packet() would call run_cmd_parser() with a NULL cmd_parser
value, which would lead to an unsupported packet ("$#00") being sent,
which could confuse the gdb client.

This also has a side-effect of speeding up the initial connection with
gdb.
