Fix crash when switching profiles

rescan_packets() starts a new dissection session by free'ing the
previous state and creating a new one. A reference to the old session
was not updated though.

This is the only place where epan is overwritten. After init, col_init
will at some point initialize cf->cinfo.epan with a cf->epan.
