[NETPOLL]: Fix TX queue overflow in trapped mode.
CONFIG_NETPOLL_TRAP causes the TX queue controls to be completely bypassed in
the netpoll's "trapped" mode which easily causes overflows in the drivers with
short TX queues (most notably, in 8139too with its 4-deep queue). So, make
this option more sensible by making it only bypass the TX softirq wakeup.
