channel: Detect bad usage of libssh2_channel_process_startup

Browse Source 
A common novice programmer error (at least among those using the
wrapping Perl module Net::SSH2), is to try to reuse channels.

This patchs detects that incorrect usage and fails with a
LIBSSH2_ERROR_BAD_USE error instead of hanging.
