The HW release can fail and leave the system in limbo state, where SRQ is removed from the table, but can't be destroyed later. In every reentry, the initial xa_erase_irq() check will fail. Rewrite the erase logic to keep index, but don't store the entry itself. By doing it, we can safely reinsert entry back in the case of destroy failure.

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.
