dasd: use the atomic queue limits API

Browse source

Pass the constant limits directly to blk_mq_alloc_disk, set the nonrot
flag there as well, and then use the commit API to change the transfer
size and logical block size dependent values.

This relies on the assumption that no I/O can be pending before the
devices moves into the ready state and doesn't need extra freezing
for changes to the queue limits.
