bnxt_en: Allocate the max bp->irq_tbl size for dynamic msix allocation

If dynamic MSIX allocation is supported, additional MSIX can be
allocated at run-time without reinitializing the existing MSIX entries.
The first step to support this dynamic scheme is to allocate a large
enough bp->irq_tbl if dynamic allocation is supported.
