bnxt_en: delay pci_alloc_irq_vectors() in the AER path

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().
