media: bdisp: fix memleak on release
commit 11609a7e21f8cea42630350aa57662928fa4dc63 upstream.
If a process is interrupted while accessing the video device and the
device lock is contended, release() could return early and fail to free
related resources.
Note that the return value of the v4l2 release file operation is
ignored.
