The problem I try to solve here is that on the caller side (nvme/035) we don't know yet the usable filesystem size. We only the size of the nvme_img_size. If we want to move this logic to the caller side we need split _xfs_run_fio_verify_io() into steps. The first step which creates the fileystem and the second one which runs fio. I don't know if this is worth doing it though.

The usable capacity of the filesystem is less than the raw partition/device size due to the additional meta/log data. Ensure that the job size for fio is not exceeding the limits. Because we have hard coded the path where we mount the filesystem and don't want to expose this, we just update max size inside _xfs_run_fio_verify_io(). No need to leak this into the caller.
