ui-primary-storage: hide provider if Linstor protocol (#5672)

* ui-primary-storage: hide provider if Linstor protocol

If Linstor protocol is selected it makes no sense to show other
providers as Linstor only works with the Linstor provider.

This was removed with the fix for #5613, that probably resulted from a
bad merge resolving from my part.
