Subject: [PATCH] media: i2c: rdacm2: Remove an incorrect fwnode_handle_put() call

The commit in Fixes has removed an fwnode_handle_put() call in the error
handling path of the probe.

Remove the same call from the remove function.

Fixes: 1029939b3782 ("media: v4l: async: Simplify async sub-device fwnode matching")

/!\   This patch is highly speculative. Review with care.   /!\

If it is correct, it is likely that other similar issue lurk in commit
1029939b3782. I've not looked in detail and my cocci script did not
trigger on them but drivers/media/i2c/max9286.c also looks like a
similar candidate.
