scsi: aacraid: Reply queue mapping to CPUs based on IRQ affinity
Fix the I/O hang that arises because of the MSIx vector not having a mapped
online CPU upon receiving completion.
SCSI cmds take the blk_mq route, which is setup during init. Reserved cmds
fetch the vector_no from mq_map after init is complete. Before init, they
have to use 0 - as per the norm.
