Setting `physicalFormat` logs error on success

[jolonf]

Setting AudioStream.physicalFormat logs an error even though it was successful.

if should be guard:

SimplyCoreAudio/Sources/SimplyCoreAudio/Public/AudioStream.swift

Lines 109 to 111 in ba8b651

 if noErr == setStreamPropertyData(kAudioStreamPropertyPhysicalFormat, andValue: &asbd) { 
     os_log("Error setting physicalFormat to %@.", log: .default, type: .debug, String(describing: newValue)) 
 } 

AudioStream.virtualFormat has the same typo.
