qcacld-3.0: Remove hif_ctx check during the driver cleanup

When inactivity timer on the interface's expires it closes all the
cds modules, when rmmod is given after the modules are closed hif_ctx
will be null. There is a invalid check during the driver remove for
valid hif_ctx which is blocking from the proper cleanup of the driver.

Since hif_ctx is not used any more during the driver remove function.
Remove hif_ctx validation during the driver unload.
