Subject: [PATCH 3.13 20/46] SUNRPC: Fix a pipe_version reference leak

3.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <trond.myklebust@...marydata.com>

commit e9776d0f4adee8877145672f6416b06b57f2dc27 upstream.

In gss_alloc_msg(), if the call to gss_encode_v1_msg() fails, we
want to release the reference to the pipe_version that was obtained
earlier in the function.

Fixes: 9d3a2260f0f4b (SUNRPC: Fix buffer overflow checking in...)
