====================
r8152: fix side effect

v3:
Update the commit message for patch #1.

v2:
Replace patch #2 with "r8152: remove calling netif_napi_del".

v1:
The commit 0ee1f4734967 ("r8152: napi hangup fix after disconnect")
add a check to avoid using napi_disable after netif_napi_del. However,
the commit ffa9fec30ca0 ("r8152: set RTL8152_UNPLUG only for real
disconnection") let the check useless.

Therefore, I revert commit 0ee1f4734967 ("r8152: napi hangup fix
after disconnect") first, and add another patch to fix it.
