smb3 client: add missing tracepoint for unsupported ioctls

Browse source

In debugging a recent problem with an xfstest, noticed that we weren't
tracing cases where the ioctl was not supported.  Add dynamic tracepoint:
    "trace-cmd record -e smb3_unsupported_ioctl"
and then after running an app which calls unsupported ioctl,
"trace-cmd show"would display e.g.
      xfs_io-7289    [012] .....  1205.137765: smb3_unsupported_ioctl: xid=19 fid=0x4535bb84 ioctl cmd=0x801c581f
