Currently dfs offload command is sent during event registration
when psoc object is created. Dfs offload command is sent by accessing
pdev object, as pdev object during this time may not be created
or maybe in logically deleted state and sending command may fail.
This failure may cause wifi_dfs_psoc_enable and thereby effecting
other module objects.
To fix this, avoid using pdev objects during psoc enable, and send
pdev object specific command when pdev is created.
