setlan: Remove registration of handler for Set Channel Access

Presently through set channel access command we apply the
network changes which is not a standard BMC implementation.
It was decided that we should apply the network changes
with the timer based approach.
Timer based implementation would be done in later commits.
This commit only removes the registration handler for
set channel access command.
