cnss2: Skip suspend from client side for pcie switch case

Browse Source 
Follow 'commit Ic63fd054788 ("pci: msm: Fix for PCIe
suspend/resume for QPS615 PCIe switch")'

As suspend has been controlled by pcie driver for PCIe
switch case, skip suspend from client side. Otherwise
it may cause stability issue.
