Summary:                    lack of locking in dahdi_request()
Description: 
In dahdi_request(), iflist / ifend are acceded without any lock taken -- or
alternatively pri->crvs / pri->crvend are.

I don't know if/when those can be modified, especially regarding crv. For
iflist/ifend, maybe reloads are concerned, and also pseudo channels, which
I don't know what they are used for.

Some code review. I don't think this could cause a real issue *for me* so I
don't plan to try to trigger this potential issue on a test plateform.

I leave it to others to evaluate if this could cause a real world issue.
