media: imx: vdic: Restore default case to prepare_vdi_in_buffers()
Restore a default case to prepare_vdi_in_buffers() to fix the following
smatch errors:
drivers/staging/media/imx/imx-media-vdic.c:236 prepare_vdi_in_buffers() error: uninitialized symbol 'prev_phys'.
drivers/staging/media/imx/imx-media-vdic.c:237 prepare_vdi_in_buffers() error: uninitialized symbol 'curr_phys'.
drivers/staging/media/imx/imx-media-vdic.c:238 prepare_vdi_in_buffers() error: uninitialized symbol 'next_phys'.
Fixes: 6e537b58de772 ("media: imx: vdic: rely on VDIC for correct field order")
