[PATCH] crypto: call zlib end functions on deflate exit path

Browse Source 
In the deflate_[compress|uncompress|pcompress] functions we call the
zlib_[in|de]flateReset function at the beginning.  This is OK.  But when we
unload the deflate module we don't call zlib_[in|de]flateEnd to free all
the zlib internal data.  It looks like a bug for me.  Please, consider the
attached patch.
