[ Upstream commit 5895e70f2e6e8dc67b551ca554d6fcde0a7f0467 ] Previously, all IB dev resources are initialized on driver load. As they are not always used, move the initialization to the time when they are needed. To be more specific, move PD (p0) and CQ (c0) initialization to the time when the first SRQ is created. and move SRQs（s0 and s1) initialization to the time first QP is created. To avoid concurrent creations, two new mutexes are also added.

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.
