This tells fio to not try to use POSIX calls on "files" specified for an SPDK engine. Note that w/o DISKLESSIO option set, fio would figure out that "*" wasn't a real file. With this option set, we now need to explicitly set its real_file_size to 0 to tell fio to ignore it. Found by Karol Latecki - he noticed that when specifying lvols in the form "lvs/lvol" that fio would create an empty "lvs" directory. Adding this flag prevents things like this from happening.
