mlx5_ib_reg_user_mr called mlx5_ib_dereg_mr in case of MR population
failure. This resulted in a NULL dereference as ibmr->device wasn't
initialized yet.
We address this by adding an internal dereg_mr function that can handle
partially initialized MRs, and fixing clean_mr to work on partially
initialized MRs.
Fixes: ff740aefec ("IB/mlx5: Decouple MR allocation and population flows")

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
