The call to nla_nest_start calls nla_put which can lead to a NULL
return so it's possible for attr to become NULL and we can potentially
get a NULL pointer dereference on attr. Fix this by checking for
a NULL return.
Detected by CoverityScan, CID#1466125 ("Dereference null return")
Fixes: 955dc68cb9b2 ("net/ncsi: Add generic netlink family")
