net: hns3: add NULL pointer check for hns3_set/get_ringparam()

Browse source

When pci devices init failed and haven't reinit, priv->ring is
NULL and hns3_set/get_ringparam() will access priv->ring. it
causes call trace.

So, add NULL pointer check for hns3_set/get_ringparam() to
avoid this situation.
