crypto/openssl: fix extra bytes written at end of data

Browse Source 
Extra bytes are being written at end of data while process standard
openssl cipher encryption. This behaviour is unexpected.

This patch disable the padding feature in openssl library, which is
causing the problem.

Fixes: d61f70b4c918 ("crypto/libcrypto: add driver for OpenSSL library")
