Linux 5.7 compat: blk_alloc_queue()
Commit https://github.com/torvalds/linux/commit/3d745ea5 simplified the blk_alloc_queue() interface by updating it to take the request queue as an argument. Add a wrapper function which accepts the new arguments and internally uses the available interfaces. Other minor changes include increasing the Linux-Maximum to 5.6 now that 5.6 has been released. It was not bumped to 5.7 because this release has not yet been finalized and is still subject to change. Added local 'struct zvol_state_os *zso' variable to zvol_alloc.
