[PATCH] loadb: Properly indicate aborted kermit transfer

When k_recv() returns zero it indicates that kermit transfer was aborted. Function do_load_serial_bin() (caller of load_serial_bin()) interprets value ~0 as aborted transfer, so properly propagates information about aborted transfer from k_recv() to do_load_serial_bin().
