fscrypt: work on block_devices instead of request_queues
request_queues are a block layer implementation detail that should not
leak into file systems. Change the fscrypt inline crypto code to
retrieve block devices instead of request_queues from the file system.
As part of that, clean up the interaction with multi-device file systems
by returning both the number of devices and the actual device array in a
single method call.
