Restoring a corrupted collection entry (like an out of range ID) is being ignored and treated as success. More specifically, a vgic_its_restore_cte failure is treated as success by vgic_its_restore_collection_table. vgic_its_restore_cte uses positive and negative numbers to return error, and +1 to return success. The caller then uses "ret > 0" to check for success. Fix this by having vgic_its_restore_cte only return negative numbers on error. Do this by changing alloc_collection return codes to only return negative numbers on error.

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.
