Subject: [PATCH] hwcomposer: Force close bypass MDP pipes on suspend.

Since SF wont compose when device is on suspend mode, MDP_UNSET can
be called to close all allocated bypass pipes.

Change-Id: Ia4610c34e6d89028f8b3400af023296c459dd8d1
(cherry picked from commit 32a9e25b699d7abde661f3ad947ed58a09a1b132)
