[PATCH 2/2] media: atomisp-ov2680: properly set the vts value

[Mauro Carvalho Chehab]

The vts value should be set before being checked, as otherwise a
warning will arise:

	drivers/staging/media/atomisp/i2c/atomisp-ov2680.c: In function 'ov2680_set_fmt':
	drivers/staging/media/atomisp/i2c/atomisp-ov2680.c:873:33: warning: 'vts' may be used uninitialized
	[-Wmaybe-uninitialized]
	  873 |         if (dev->exposure > vts - OV2680_INTEGRATION_TIME_MARGIN)
