rgw: Fix typo in comment

[simransinghal]

Replace "dont" with "don't". "Dont" is not same as "Do not" or "Don't".

Typos in comments are only fixed if there is also a code fix at the same location.
And then I forgo the very long discussion we had about 1 year ago about all kind of colloquialisms, UK vs US english, and other languages style prefferences.
So might I polittely suggest to close this.

@wjwithagen May be this one. #16705. :-)

But dont is incorrect I think.

Yes, "dont" is not a dictionary word.
And even Linux kernel style does not prefer such kind of mistakes. So, it's good if we change this.
