smdk4412-common: camera: don't defer picture if CAF is in progress

CAF is considerably slower than Auto or Touch Focus and since we
are deferring the picture while CAF is in progress, there are
delays while taking the picture and these delays are sometimes
huge.

Disregard the CAF state since we could Touch to Focus if required.
