net: systemport: Clear status to reduce spurious interrupts

Do something similar to commit 2a1d6f196f99 ("net: bcmgenet: clear
status to reduce spurious interrupts") and clear interrupts right before
servicing them. This reduces the number of interrupts by 10K
interrupts/sec for a TX TCP session 1Gbits/sec.
