eth: 3c515: replace cleanup_module with __exit

update old legacy cleanup_module from the file with __exit
module as per kernel code practices and restore the #ifdef
MODULE condition to allow successful compilation as a built
-in driver.

The file had an old cleanup_module still in use which could
be updated with __exit module function although its init_module
is indeed newer however the cleanup_module was still
using the older version of exit.

To set proper exit module function replace cleanup_module
with __exit corkscrew_exit_module to align it to the
kernel code consistency.
