1. Add missing semicolon between "warn" and "return" to make sure

the line continuation backslash doesn't cause "warn" to print "return".
2. Group "warn" and "return" together as the "return 1" should be
   performed only if the "kldload nfsclient" also failed (and not
   already if the "vfs.nfs" sysctl(8) check failed).
