[ycabled] fix naming error for error condition for CLI handling (soni…

…c-net#302)

Signed-off-by: vaibhav-dahiya vdahiya@microsoft.com
This PR fixes a typo/error condition when read_side is not 1 or 2 or -1, for a case where NIC side is plugged into the ToR and a user configures a CLI for
sudo config mux hwmode state active/standby <port>,
in such a scenario we can trigger this
xcvrd_config_hwmode_state_cmd_sts_tbl attribute error.
