[PATCH 6/7] bsearch.3: Fix intermediate type and remove unneeded casts

[Alejandro Colomar <colomar.6.4.3@gmail.com>]

Casting `const void *` to `struct mi *` should result in a warning if
done implicitly.  The explicit cast was probably silencing that warning.
`const` can and should be kept.
Now, casting `const void *` to `const struct mi *` is done implicitly.
