Subject: [PATCH] btrfs-progs: scrub status: only report limits if at least one
 exists

On multi-device filesystems, scrub status should report "some limits
set" if at least one device has a scrub limit set.

However, with btrfs-progs 6.6.3, this was being reported regardless of
whether any limit actually being set:

# sudo btrfs scrub limit /more/butter
    UUID: 989129d9-c96f-4d52-9d68-cbb6d9b2c499
    Id  Limit       Path
    --  -----  ---------
     1      -  /dev/sdc1
     2      -  /dev/sdd1

# sudo btrfs scrub status /more/butter/
    UUID:             989129d9-c96f-4d52-9d68-cbb6d9b2c499
    Scrub started:    Mon Jan 15 02:00:30 2024
    Status:           running
    Duration:         6:23:19
    Time left:        0:49:08
    ETA:              Mon Jan 15 09:12:57 2024
    Total to scrub:   9.83TiB
    Bytes scrubbed:   8.72TiB  (88.64%)
    Rate:             397.47MiB/s (some device limits set)
    Error summary:    no errors found

Fix it by only setting `limit` to the special marker value 1 if at least
one actual limit is found.
