dm table: establish queue limits by copying table limits
Copy the table's queue_limits to the DM device's request_queue. This
properly initializes the queue's topology limits and also avoids having
to track the evolution of 'struct queue_limits' in
dm_table_set_restrictions()
Also fixes a bug that was introduced in dm_table_set_restrictions() via
commit ae03bf639a5027d27270123f5f6e3ee6a412781d. In addition to
establishing 'bounce_pfn' in the queue's limits blk_queue_bounce_limit()
also performs an allocation to setup the ISA DMA pool. This allocation
resulted in "sleeping function called from invalid context" when called
from dm_table_set_restrictions().
