media: tm6000: Fix unused value in vidioc_try_fmt_vid_cap()
[ Upstream commit d682869daa23938b5e8919db45c4b5b227749712 ]
Coverity warns of an unused value:
assigned_value: Assign the value of the variable f->fmt.pix.field
to field here, but that stored value is overwritten.
before it can be used.
919 field = f->fmt.pix.field;
920
value_overwrite: Overwriting previous write to field with
the value of V4L2_FIELD_INTERLACED.
921 field = V4L2_FIELD_INTERLACED;
