[ Upstream commit b9f59a24ba35a7d955a9f8e148dd9f85b7b40a01 ]
Currently the condition of unmapping sdb in error path is not exactly
the same as the condition of mapping in alloc_user_qp_db(). This may
cause a problem of unmapping an unmapped db in some case, such as
when the QP is XRC TGT. Unified the two conditions.
Fixes: 90ae0b57e4 ("RDMA/hns: Combine enable flags of qp")

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.
