media: streamzap: prevent processing IR data on URB failure
If streamzap_callback() receives an urb with any non-critical error
status, i.e. any error code other than -ECONNRESET, -ENOENT or -ESHUTDOWN,
it will try to process IR data, ignoring a possible transfer failure.
Make streamzap_callback() process IR data only when urb->status is 0.
Move processing logic to a separate function to make code cleaner and
more similar to the URB completion handlers in other RC drivers.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
