different error messages for mkfs.xfs -ssize

[Wengang Wang <wen.gang.wang@xxxxxxxxxx>]

Hi experts,

I got different error messages when provide different value for -ssize.
Why the error messages are different? They are different but no one is
containing more info than the other.

[root@desk test-xfsprogs]# mkfs.xfs -ssize=256 /dev/sda10 -f 2>&1 |head -n 1
illegal sector size 256
[root@desk test-xfsprogs]# mkfs.xfs -ssize=3072 /dev/sda10 -f 2>&1 |head -n 1
Illegal value 3072 for -s sectsize option

regards,
wengang.
