octeontx2-pf: Clear RSS enable flag on interace down

Browse Source 
[ Upstream commit f12098ce9b ]

RSS configuration can not be get/set when interface is in down state
as they required mbox communication. RSS enable flag status
is used for set/get configuration. Current code do not clear the
RSS enable flag on interface down which lead to mbox error while
trying to set/get RSS configuration.
