Zhengchao Shao 4b71f2b543 9p/rdma: unmap receive dma buffer in rdma_request()/post_recv()
[ Upstream commit 74a25e6e916cb57dab4267a96fbe8864ed21abdb ]

When down_interruptible() or ib_post_send() failed in rdma_request(),
receive dma buffer is not unmapped. Add unmap action to error path.
Also if ib_post_recv() failed in post_recv(), dma buffer is not unmapped.
Add unmap action to error path.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
