[PATCH 2/7] media: v4l2-mem2mem: Remove WARN_ON() in v4l2_m2m_job_finish()

[Detlev Casanova <detlev.casanova@collabora.com>]

This warning was added because there was no way, for drivers that support
holding capture buffers to mark jobs done correctly without calling
v4l2_m2m_buf_done_and_job_finish().

Now that v4l2_m2m_buf_done_manual() has been introduced, it has become
possible and drivers can use it with v4l2_m2m_job_finish() for finer
grained buffer management.
