Commit4fa1834559("scsi: qla2xxx: Utilize pci_alloc_irq_vectors/ pci_free_irq_vectors calls.") use pci_alloc_irq_vectors() to replace pci_enable_msi() but it didn't handle the return value correctly. This bug make qla2x00 always fail to setup MSI if MSI-X fail, so fix it. BTW, improve the log message of return value in qla2x00_request_irqs() to avoid confusion.

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.
