Remove CFRelease() calls in host_get_name()

[directmusic]

In the Core Foundation functions any time the word "Get" is used we do not have ownership and do not need to call CFRelease(). Fixes #304

formatting aside (and that it came from main not next so blew out a tiny formatting change on next) this change looks correct to me. I may tweak it a touch tomorrow to fix formatting and remove the string change I had made on the hostname. but @defiantnerd wdyt?

And thanks @directmusic.

@defiantnerd we should review the rest of the AUV2 code to make sure we aren't making a similar error elsewhere.

Actually had a moment before end of day and pushed up a clang format fix and also the regression of next vs main

if CI passes lets ask @defiantnerd to look.

Thank you!!

Yeah, fix is fine. Thank you very much, @directmusic !
And yes, we should give AUv2 another review for this issue.
