[PATCH] crypto/qat: fix docsis segmentation fault

Currently if AES or DES algorithms fail for Docsis test suite,
a segmentation fault occurs when cryptodev_qat_autotest is ran.
This is due to a duplicate call of EVP_CIPHER_CTX_free for the
session context. Ctx is freed firstly in the bpi_cipher_ctx_init
function and then again at the end of qat_sym_session_configure_cipher
function.
This commit fixes this bug by removing the first instance
of EVP_CIPHER_CTX_free, leaving just the dedicated function in
the upper level to free the ctx.
