Shaun Ruffell f7925643de dahdi: Prevent unloadable module on failed open. ...

If chan->span->ops->open() fails then the reference count of the module
implementing the board driver will not be decremented.  The result is a
module that would always be "in use" and unloadable.

This change makes sure to release that reference when open failed.
