[media] staging: media: davinci: vpfe: make sure all the buffers are released
from commit-id: b3379c6201bb3555298cdbf0aa004af260f2a6a4
"vb2: only call start_streaming if sufficient buffers are queued"
the vb2 framework warns on (WARN_ON()) if all the active buffers
are not released when streaming is stopped, initially the vb2 silently
released the buffer internally if the buffer was not released by
the driver.
This patch fixes following issue:
