With the below commit, common isr is split into tx and rx, but in
rx isr tx interrupt is also disabled. So tx packets are not handled
during rx interrupts and rx napi completion. Fixing by disabling on
rx interrupt in rx isr.
Fixes: c03abd84634d ("net: ethernet: cpsw: don't requests IRQs we don't use")
