Kernel commit dea2903719283c156b53741126228c4a1b40440f exposed (and
8d419f
renamed) CIFS_MAGIC_NUMBER as CIFS_SUPER_MAGIC along with
8d419f
SMB2_SUPER_MAGIC.

This fixes the following build fail on current Fedora Rawhide:

8d419f
Filesystem found in kernel header but not in filesystems-gperf.gperf: SMB2_SUPER_MAGIC
8d419f
```
8d419f
