[Spice-devel] [spice-gtk v1 08/10] file-transfer: increase reference for channel-main

channel-main uses the SpiceFileTransferTask reference given in the
hash table provided by spice_file_transfer_task_create_tasks(). That
means SpiceFileTransferTask is not holding a reference for itself but
it relies on it due the async calls it provides.

This patch increases the reference of each SpiceFileTransferTask for
the hash table which will be unref'ed by channel-main in
file_transfer_operation_task_finished(); the original reference is
kept to SpiceFileTransferTask to be freed after the finish signal is
emitted on spice_file_transfer_task_close_stream_cb().

This patch fixes some critical warnings as we have two g_object_unref
but only one reference.
