Simplify 'xhci_try_enable_msi()' and reduce unnecessary function calls. xHCI driver first tries to allocate 'num_online_cpu()' number of MSI-X vectors, if that fails it falls back to a single MSI vector. There is no good reason for this, we currently only support a primary interrupter. However, we are still interested in knowing if there are more vectors available, which will be utilized once we get secondary interrupter support. Call 'pci_alloc_irq_vectors()' once (with MSI-X and MSI flag), instead of separately for MSI-X and MSI. And accept any number of MSI-X or MSI vectors between 1 and 'num_online_cpu()'.

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.
