qca-nss-drv: Avoid recreating debugfs entry virt_if

Browse Source 
Everytime a virtual interface is created/destroyed, nss driver
tries to create a debugfs entry, without checking if it exists.
Prevent creation if it already exists. This will also prevent the
annoying kernel warning.

'virt_if' in directory 'stats' already present!
