Revert "r8169: don't try to disable interrupts if NAPI is, scheduled already"
This reverts commit 7274c4147afbf46f45b8501edbdad6da8cd013b9.
Ken reported that RTL8125b can lock up if gro_flush_timeout has the
default value of 20000 and napi_defer_hard_irqs is set to 0.
In this scenario device interrupts aren't disabled, what seems to
trigger some silicon bug under heavy load. I was able to reproduce this
behavior on RTL8168h. Fix this by reverting 7274c4147afb.
Fixes: 7274c4147afb ("r8169: don't try to disable interrupts if NAPI is scheduled already")
