gdbstub: don't complain about preemptive ACK chars
When starting a remote connection GDB sends an '+':
/* Ack any packet which the remote side has already sent. */
remote_serial_write ("+", 1);
which gets flagged as a garbage character in the gdbstub state
machine. As gdb does send it out lets be permissive about the handling
so we can better see real issues.
