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.

camera: Fix loss of focus mode between shots

exynos_camera->focus_mode can't be relied upon to verify the previous
state, since a snapshot will reset the focus state. This was causing
any mode besides auto-focus (enum 0) to fail after the first photo
was taken, including the default continuous-picture.

Always make sure the focus-mode is up to date when set_params is
called
