Coverity points out that by using EMPTYSTR(type) we are guarding against
the possibility that it could be NULL; however, based on how 'type' was
initialized to NULL, then using nested ternary if-then-else's (?:?:)
setting either "ipv4", "ipv6", or "" - there is no way it could be NULL.
Since "-" is supposed to mean something empty in a field - modify the
nested ternary to an easier to read/process if-then-else leaving the
initialization to NULL to mean "-" in the formatted output.
Also changed the name from 'type' to 'typestr'.
