#216: libssh2_scp_recv() / libssh2_scp_send(): incorrect error code

---------------------------+------------------------------------------------
 libssh2_session_last_error() after libssh2_scp_recv()/libssh2_scp_send()
 may return LIBSSH2_ERROR_SOCKET_NONE on error.

 Sample perl script:

 {{{
 #!/usr/bin/perl

 use strict;
 use Net::SSH2;

 my $ssh2 = Net::SSH2->new();

 $ssh2->connect('localhost');
 $ssh2->auth_publickey('user', './id_dsa.pub', './id_dsa');

 if (!$ssh2->scp_put($0, '/nonexistent/test')) {
    my ($err_code, $err_name, $err_string) = $ssh2->error();
    warn "scp_put error: $err_code $err_name $err_string";
 }

 if (!$ssh2->scp_get('/nonexistent/test')) {
    my ($err_code, $err_name, $err_string) = $ssh2->error();
    warn "scp_get error: $err_code $err_name $err_string";
 }
 }}}

 libssh2_scp_recv() returns not really useful code 0:

 {{{
 scp_put error: 0 at ./test.pl line 14.
 scp_get error: 0 at ./test.pl line 18.
 }}}

 with attached patch:
 {{{
 scp_put error: -28 LIBSSH2_ERROR_SCP_PROTOCOL failed to send file at
 ./test.pl line 14.
 scp_get error: -28 LIBSSH2_ERROR_SCP_PROTOCOL Failed to recv file at
 ./test.pl line 18.
 }}}
