[linux-dvb] af9005/mt2060 module unload failure

[Olaf Titz]

This sequence:
 modprobe dvb_usb_af9005
 sleep 60
 modprobe -r dvb_usb_af9005

leaves the following residue:
Module                  Size  Used by
mt2060                  5572  4294967295
(the number is "unsigned int" for -1)

Subsequent re-loading of the modules succeeds but then accessing the
tuner fails, likely due to this error.

Device is a Terratec Cinergy T USB XE, driver from current HG.
