SnapdragonCamera: Open camera in init for improve start preview KPIs

When switch from VideoModule to PhotoModule, opencamera will run in
onResume rather than init() and start preview must be executed after
open camera.This lead to start preview slowly.

Open camera when module init for run start preview as early as possible.
so the flag mIsModuleSwitchInProgress isn't needed.
Reference similar action in VideoModule's init().
