[PATCH 2/2] tgtadm: display unsupported operation name explicitly

[Zhang Yanfei <zhangyanfei.yes@gmail.com>]

From: Zhang Yanfei <zhangyanfei@cn.fujitsu.com>

When we specify an unsupported operation type for some mode,
tgtadm will display the error message which contains the
unsupported operation type value. The patch changes to
display the operation name which is more explicit. Also
change the word 'option' to 'operation'.
