scsi: Expand all create*_workqueue() invocations

The workqueue maintainer wants to remove the create*_workqueue() macros
because these macros always set the WQ_MEM_RECLAIM flag and because these
only support literal workqueue names. Hence this patch that replaces the
create*_workqueue() invocations with the definition of this macro. The
WQ_MEM_RECLAIM flag has been retained because I think that flag is necessary
for workqueues created by storage drivers. This patch has been generated by
running spatch and git clang-format. spatch has been invoked as follows:

spatch --in-place --sp-file expand-create-workqueue.spatch $(git grep -lEw 'create_(freezable_|singlethread_|)workqueue' */scsi */ufs)

The contents of the expand-create-workqueue.spatch file is as follows:

@@
expression name;
@@
-create_workqueue(name)
+alloc_workqueue("%s", WQ_MEM_RECLAIM, 1, name)
