Use correct counter after invoking stitched AES-NI GCM code. Commit a3d9528e9e212e0dcda30dcb561092c3b3a69010 has a bug that could cause counters to be reused if |$avx=2| were set in the AES-NI AES-GCM assembly code, if the EVP interface were used with certain coding patterns, as demonstrated by the test cases added in a5ee83f67e83d4065d1aa40137e8dd8b1c83b3e5. This changes the encryption code in the same way the decryption code was changed in a3d9528e9e212e0dcda30dcb561092c3b3a69010. This doesn't have any effect currently since the AES-NI AES-GCM code has |$avx=0| now, so |aesni_gcm_encrypt| doesn't change the counter.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
