[PATCH v2 6/6] net/iavf: fix leak of IPsec crypto capabilities array

[Bruce Richardson <bruce.richardson@intel.com>]

The security context setup allocates a crypto capabilities array and
stores it in iavf_sctx->crypto_capabilities. However, the security
context destroy path frees iavf_sctx and sctx directly, without first
freeing that array.

Fix this by freeing iavf_sctx->crypto_capabilities in
iavf_security_ctx_destroy() before freeing the security context itself.
