Breno Leitao 614accf545 net: netpoll: use synchronize_net() instead of synchronize_rcu() ...

Replace synchronize_rcu() with synchronize_net() in __netpoll_free().

synchronize_net() is RTNL-aware and will use the more efficient
synchronize_rcu_expedited() when called under RTNL lock, avoiding
the potentially expensive synchronize_rcu() in RTNL critical sections.

Since __netpoll_free() is called with RTNL held (as indicated by
ASSERT_RTNL()), this change improves performance by reducing the
time spent in the RTNL critical section.
