Chengmc e648d65af8 [allocator] lock ion heap detection operation ...

When in multi-codecs cases, the check_sysfs_iommu function reenters
with high probability, so some codec instances may fail to obtain
the correct memory type.

The root cause is scandir call in find_dir_in_path function. For
efficiency consideration it is better to lock ion_heap_id value.
