media: dvb-core: fix a memory leak bug
In dvb_create_media_entity(), 'dvbdev->entity' is allocated through kzalloc(). Then, 'dvbdev->pads' is allocated through kcalloc(). However, if kcalloc() fails, the allocated 'dvbdev->entity' is not deallocated, leading to a memory leak bug. To fix this issue, free 'dvbdev->entity' before returning -ENOMEM.
