[ Upstream commit a8c2d3932c1106af2764cc6869b29bcf3cb5bc47 ] It can be needed to have some MSI-X allocated as static and rest as dynamic. For example on PF VSI. We want to always have minimum one MSI-X on it, because of that it is allocated as a static one, rest can be dynamic if it is supported. Change the ice_get_irq_res() to allow using static entries if they are free even if caller wants dynamic one. Adjust limit values to the new approach. Min and max in limit means the values that are valid, so decrease max and num_static by one. Set vsi::irq_dyn_alloc if dynamic allocation is supported.

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.
