The store to ctx->cm_id was based on the idea that _ucma_find_context() would not return the ctx until it was fully setup. Without locking this doesn't work properly. Split things so that the xarray is allocated with NULL to reserve the ID and once everything is final set the cm_id and store. Along the way this shows that the error unwind in ucma_get_event() if a new ctx is created is wrong, fix it up.

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.
