[media] ivtv: Make two ivtv_msleep_timeout calls uninterruptable

Two ivtv_msleep_timeout() calls are incorrectly flagged as interruptable. The
first is in the init sequence for a capture and is required for stable
hardware setup. The second is at the end of the capture and used to handle the
last data transfer. Failure to wait for this last transfer can result in stale
data being read at the start of the next capture.
