video: tegra: host: optimize nvhost pin operations
Pin both relocs and gathers in single pin_job_mem() call.
Use nvmap_pin_array() to avoid extra pin operation and
per-handle locking overhead.
Remove used relocs from the nvhost_job to avoid extra loop
iterations inside do_relocs.
Use fast nvmap functions _nvmap_duplicate_handle_id()
_nvmap_free().
