audio policy: fix device selection in startInput()android-4.3_r2android-4.3_r1.1android-4.3_r1android-4.3_r0.9.1android-4.3_r0.9jb-mr2-release

Check again input device selection when capture starts in case
conditions have changed since the input stream was opened.

This is related to but does not fix issue 8761558. It makes the
selection of BT SCO device consistent.
