blk-mq: initial support for multiple queue maps Add a queue offset to the tag map. This enables users to map iteratively, for each queue map type they support. Bump maximum number of supported maps to 2, we're now fully able to support more than 1 map.

blk-mq: code clean-up by adding an API to clear set->mq_map set->mq_map is now currently cleared if something goes wrong when establishing a queue map in blk-mq-pci.c. It's also cleared before updating a queue map in blk_mq_update_queue_map(). This patch provides an API to clear set->mq_map to make it clear.

blk-mq: Allow PCI vector offset for mapping queues The PCI interrupt vectors intended to be associated with a queue may not start at 0; a driver may allocate pre_vectors for special use. This patch adds an offset parameter so blk-mq may find the intended affinity mask and updates all drivers using this API accordingly.
