Only invoke .lower() on non-None protocols
When using source group based security group rules (rather than CIDR
based ones), it's permissible to not set a protocol and port. However,
Nova would always try to convert the protocol to lower case, which would
fail if the protocol wasn't set.
Fixes bug 1010514
