[ Upstream commit c1be62923d4d86e7c06b1224626e27eb8d9ab32e ]
Closing GPR port before graph close can result in un handled notifications
from DSP, this results in spam of errors from GPR driver as there is no
one to handle these notification at that point in time.
Fix this by closing GPR port after graph close is finished.
