<div class='commit-subject'>greybus: audio: Remove un-necessary goto statement</div><div class='commit-msg'>For most of the helper functions, goto statement is widely used.  It was
originally used with an intent of single exit point for the function
with some cleanup required. This is no more the case. So, simplify code
by avoiding un-necessary gotos.
