dahdi: Allow dahdi_span_ops.[chan|span]config and startup to block.
This change ensures that the dahdi_span_ops callbacks are not called
with any spinlocks held, and that the module is pinned in memory, and
also passes the struct file * pointer to the callbacks.
Passing the file pointer to the callbacks allows the board drivers to
check any flags on the file descriptor used to configure the
span/channel. The intent here is to allow dahdi_config to open the
/dev/dahdi/ctl file in a non-blocking mode in case there is a lengthy
processes that needs to happen as part of configuration.
