qcacmn: Prevent NOC/Link Access in resume when Link is down

propagation from qcacld-2.0 to qcacmn.

PCIe link training failure will not be indicated to cnss client driver
as a link down indication.
In System/Runtime PM resume callbacks, client driver will access the target
registers results in L2 errors.
Fix it by ensuring the PCIe link resume training is completed by reading
config space device-id.
