Subject: [PATCH net-next v2 2/2] qed: Fix use of incorrect shmem address.

Incorrect shared memory address is used while deriving the values
for tc and pri_type. Use shmem address corresponding to 'oem_cfg_func'
where the management firmare saves tc/pri_type values.

Fixes: cac6f691 ("qed: Add support for Unified Fabric Port")
