cnss2: Avoid to call NULL plat_env

Browse Source 
For dual chip solution, first chip may fail to probe because of pcie
driver is not ready. During second chip probing, first chip may retry
to probe. So, second chip may set/get plat_env[0], first chip may
set/get plat_env[1].

If sencond chip not attached, plat_env[0] will be cleaned. When
cnss_pci_probe() is called by first chip, cnss_get_plat_priv_by_rc_num()
will call plat_env[0]. However it is already NULL.
