media: pvrusb2: Fix oops on tear-down when radio support is not present
[ Upstream commit 7f404ae9cf2a285f73b3c18ab9303d54b7a3d8e1 ]
In some device configurations there's no radio or radio support in the
driver. That's OK, as the driver sets itself up accordingly. However
on tear-down in these caes it's still trying to tear down radio
related context when there isn't anything there, leading to
dereferences through a null pointer and chaos follows.
How this bug survived unfixed for 11 years in the pvrusb2 driver is a
mystery to me.
