media: imx274: fix frame interval handling

[ Upstream commit 49b20d981d723fae5a93843c617af2b2c23611ec ]

1) the numerator and/or denominator might be 0, in that case
   fall back to the default frame interval. This is per the spec
   and this caused a v4l2-compliance failure.

2) the updated frame interval wasn't returned in the s_frame_interval
   subdev op.
