From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>
commit 1c668e1c0a0f74472469cd514f40c9012b324c31 upstream.
Static analysis Coverity had detected a potential array out-of-bounds
write issue due to the fact that MAX AFE port Id was set to 16 instead
of using AFE_PORT_MAX macro.
Fix this by properly using AFE_PORT_MAX macro.
