bna: Minor IRQ Index and Definition Change
Change details:
- Always set mbox irq index to zero and make corresponding changes in mbox
irq alloc/sync function and txrx irq index calculation. Add definition of
BNAD_INTX_TX_IB_BITMASK & BNAD_INTX_RX_IB_BITMASK and update
bnad_txrx_irq_alloc accordingly.
