cifs: Fix crash on unload of cifs_arc4.ko 

commit 51a08bdeca upstream.

The exit function is wrongly placed in the __init section and this leads
to a crash when the module is unloaded.  Just remove both the init and
exit functions since this module does not need them.

Fixes: 71c0286324 ("cifs: fork arc4 and create a separate module...")
