scsi: only access SCSIDevice->requests from one thread Stop depending on the AioContext lock and instead access SCSIDevice->requests from only one thread at a time: - When the VM is running only the BlockBackend's AioContext may access the requests list. - When the VM is stopped only the main loop may access the requests list. These constraints protect the requests list without the need for locking in the I/O code path. Note that multiple IOThreads are not supported yet because the code assumes all SCSIRequests are executed from a single AioContext. Leave that as future work.
