Subject: crypto: tcrypt - fix buffer lengths in test_aead_speed()

From: Robert Baronescu <robert.baronescu@nxp.com>


[ Upstream commit 7aacbfcb331ceff3ac43096d563a1f93ed46e35e ]

Fix the way the length of the buffers used for
encryption / decryption are computed.
For e.g. in case of encryption, input buffer does not contain
an authentication tag.
