This patch is similar to the last patch to delay the pci_alloc_irq_vectors() call in the AER path until after calling bnxt_reserve_rings(). bnxt_reserve_rings() needs to properly map the MSIX table first before we call pci_alloc_irq_vectors() which may immediately write to the MSIX table in some architectures. Move the bnxt_init_int_mode() call from bnxt_io_slot_reset() to bnxt_io_resume() after calling bnxt_reserve_rings(). With this change, the AER path may call bnxt_open() -> bnxt_hwrm_if_change() with bp->irq_tbl set to NULL. bp->irq_tbl is cleared when we call bnxt_clear_int_mode() in bnxt_io_slot_reset(). So we cannot use !bp->irq_tbl to detect aborted FW reset. Add a new BNXT_FW_RESET_STATE_ABORT to detect aborted FW reset in bnxt_hwrm_if_change().

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 reStructuredText 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.
