[media] soc_camera: fix VIDIOC_S_CROP ioctl

Sometimes VIDIOC_S_CROP ioctl doesn't work, soc-camera driver reports:
soc-camera-pdrv soc-camera-pdrv.0: S_CROP denied: getting current crop failed
The VIDIOC_G_CROP documentation states that the type field needs to be
set to the respective buffer type when querying, so the check in .g_crop()
of the subdevices returns -EINVAL if the type is not set properly. Here the
uninitialized local variable 'current_crop' is passed to the .g_crop() and
this leads to the observed error. Initialize the type field of the local
'current_crop' before get_crop call.
