[PATCH v2] i2c: qcom-geni: Keep comment why interrupts start disabled

[Andi Shyti <andi.shyti@kernel.org>]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

The to-be-fixed commit rightfully reduced a race window, but also
removed a comment which is still helpful after the fix. Bring the
comment back.

Hi,

I'm resending this patch from Wolfram so that we don't lose it. All the changes
in this v2 have been agreed during code review.

Here's the difference:
v1 -> v2:
 - Reword the comment.
 - Remove the Fixes tag.
 - Add Bjorn's r-b.
