Heiner Kallweit eabb8a9be1 Revert "r8169: don't try to disable interrupts if NAPI is, scheduled already"
This reverts commit 7274c4147a.

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 7274c4147a.
