SurfaceFlinger: reset the FB_TGT acquire fence

Browse Source 
This change makes SurfaceFlinger reset the acquire fence fd to -1 after each
call to HWComposer::commit.  The HWComposer implementation is resonsible for
closing the fd, so SurfaceFlinger should make sure not to pass it to HWC
multiple times.
