[PATCH 3/3] rust: fix datatype in docs for `module` macro arguments

[Aswin Unnikrishnan]

Remove the mention of byte array as datatype for `module` macro arguments
since the arguments are defined as string, and `alias` is a string array.

I think the original intention here was to document mainly the "type"
of the arguments (given the title of the section), i.e. the kind of
values one can write for each key.

So it would perhaps be best to give that information, e.g. "ASCII
string literal ...". Please see the code of the macro to see which
type is required for each field (e.g. is it a literal? Does it require
ASCII? ...?).

This should probably be considered a fix, so could you please add a
`Fixes:` tag and a `Cc: stable@vger.kernel.org` one in v2 (since it
does not hurt)? See e.g. what I did for your other fix I applied
already to `rust-fixes` (but note it fixes a different commit) and
https://docs.kernel.org/process/submitting-patches.html#describe-your-changes.

Thanks!

Cheers,
Miguel

Applied this one (1/3) to `rust-fixes` (tagged for stable too) --
thanks everyone!

[ Reworded slightly. ]
