filesetup: clear O_RDWR flag for verify_only write workloads

If verify_only is set we don't need to open the file with the O_RDWR flagi for write workloads. So we should clear this flag. This will help when the file is on a read-only file system. Fixes: #1681 Signed-off-by: Vincent Fu <[email protected]>
