media: dvb-usb-v2: Fix incorrect use of transfer_flags URB_FREE_BUFFER
commit 1a0c10ed7bb1 ("media: dvb-usb-v2: stop using coherent memory for
URBs") incorrectly adds URB_FREE_BUFFER after every urb transfer.
It cannot use this flag because it reconfigures the URBs accordingly
to suit connected devices. In doing a call to usb_free_urb is made and
invertedly frees the buffers.
The stream buffer should remain constant while driver is up.
