net: stmmac: selftests: Update status when disabling RSS

Browse source 
commit e715d74504352968cf24ac95476706bc911a69cd upstream.

We are disabling RSS on HW but not updating the internal private status
to the 'disabled' state. This is needed for next tc commit that will
check if RSS is disabled before trying to apply filters.

Fixes: 4647e02119 ("net: stmmac: selftests: Add selftest for L3/L4 Filters")
