Code Issues Proposed changes

Only invoke .lower() on non-None protocols

Browse Source 
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
