Extend rss_hwm_reset to reset dmabuf RSS HWM

Perform dmabuf RSS high watermark reset operation when resetting other
RSS high watermarks. Since dmabuf RSS high watermark API might not exist
in all kernel versions, implement a detection mechanism for this API
support and skip reading dmabuf_rss_hwm if the kernel does not support it.
