blk-mq: remove QUEUE_FLAG_POLL from default MQ flags 

We only support polling if we have poll queues now, but the flag is
being set by default. Remove the default QUEUE_FLAG_POLL setting, we'll
set it in blk_mq_init_allocated_queue() if we have poll queues available
for this device.

Fixes: 6544d229bf ("block: enable polling by default if a poll map is initalized")
