V4L/DVB (6997): Replace a very dirty hack on videobuf for a clean wait_event
In order to videobuf_iolock to work, mmap_mapper should be called first. Otherwise, an OOPS is generated. On some cases, .mmap file handler used to took some time to be called. On those situations, mmap_mmapper() were called after iolock. This patch properly waits for mmap_mapper to be called, otherwise generating an error.
