Subject: [PATCH] Correctly clear blocking flag after sending multipart packet

commit 7317edab61d2179febc38a2c2c4da0b951d74cbc cleared the outbound
blocking bit when send_existing() returned PACKET_NONE and *ret=0, as
opposed to before even calling send_existing(), but because *ret=1 when
sending parts 2..n of an existing packet, the bit would only be cleared
when calling libssh2_transport_write() for a new packet.

Clear the direction flag after the final part of a packet has been sent.
