Richard Mudgett 0a81d3795d chan_dahdi: Fix segfault dereferencing a NULL tech_pvt. ...

The tech support customer was using the AMI Redirect action shortly after
a call was placed.  While the channel tried to do an ast_read(), the
masquerade resulting from the channel redirect took place.  The masquerade
in the middle of the ast_read() resulted in the segfault.
