Zenghui Yu 10a52dc487 irqchip/alpine-msi: Fix off-by-one in allocation error path
[ Upstream commit ff3669a71a ]

When alpine_msix_gic_domain_alloc() fails, there is an off-by-one in the
number of interrupts to be freed.

Fix it by passing the number of successfully allocated interrupts, instead
of the relative index of the last allocated one.

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.
