Description

if lnet is not brought down properly (IE: lctl network down or lnetctl lnet unconfigure), then LNetFini():LASSERT(the_lnet.ln_refcount == 0); is hit. We need to modify this assert to account for this scenario. This wasn't a problem before because a network was always loaded irregardless. and LNetNIFini() was always called to set ln_refcoutn to 0
