igc: Remove reset adapter task for i226 during disable tsn config

I225 have limitation when programming the BaseTime register which required
a power cycle of the controller. This limitation already lifted in I226.
This patch removes the restriction so that when user configure/remove any
TSN mode, it would not go into power cycle reset adapter.

How to test:

Schedule any gate control list configuration or delete it.

Example:

1)

BASE_TIME=$(date +%s%N)
tc qdisc replace dev $interface_name parent root handle 100 taprio \
    num_tc 4 \
    map 3 1 0 2 3 3 3 3 3 3 3 3 3 3 3 3 \
    queues 1@0 1@1 1@2 1@3 \
    base-time $BASE_TIME \
    sched-entry S 0F 1000000 \
    flags 0x2

2) tc qdisc del dev $intername_name root
