Subject: [PATCH] loadb: Properly indicate aborted kermit transfer
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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().
