msm: vidc: Fix metadata buffer size issue

- Metadata buffer size is being set to zero when
  client calls set buffer requirements to video driver.
  This change fix it by properly assigning the
  metadata buffer size to video driver.
- When continuous mode enabled, do not get min_dpb
  from resource tracker for non-H264 codecs,
  for H264 codec get min_dpb from resource tracker.

msm: vidc: Free buffer pool entry and then delete address table

Free the buffer pool entry first and then delete the
address table (which will unmap the buffer with iommu)
else we might get a corner case where the entry was not
freed but the buffer is unmapped and the next buffer is
mapped with the same physical address which is still
available in the buffer pool entry, which results in
video recording failure.

gpu: ion: suppress excessive logging for expected failure cases

We expect alloc_pages to fail for high-order pages under stressed
memory conditions. It should then fall back to lower-order page
allocations but due to excessive logging the system crashes. Use
__GFP_NOWARN for high-order allocations to avoid excessive logging.

gpu: ion: Minimize allocation fallback delay

When we allocate from iommu heap we first try to allocate 1M pages. If
that fails we try 64K pages, which falls back to 4K pages. However,
we don't want to incur too much overhead when allocating with fallbacks
so we don't want the higher order page allocation to retry, perform
reclaim, or run memory compaction.

Configure the GFP flags to ensure that when we allocate pages greater
than order 0 we don't try to do any retries, reclaim, access emergency
pools, or run memory compaction. This will ensure lower memory allocation
latency for applications.

the video buffers. With this change the ion handle can be
