camera3: Don't eagerly finish configuring bidi streams more than once

Finishing all stream configuration immediately is good, but when a stream is
both input and output it attempted to finish configuring bidi streams twice.
Since all ZSL streams are bidi, when we had a ZSL stream active preview would
immediately stop working.
