via-rhine: Fix bugs in NAPI support.

[ Upstream commit 559bcac35facfed49ab4f408e162971612dcfdf3 ]

1) rhine_tx() should use dev_kfree_skb() not dev_kfree_skb_irq()

2) rhine_slow_event_task's NAPI triggering logic is racey, it
   should just hit the interrupt mask register.  This is the
   same as commit 7dbb491878a2c51d372a8890fa45a8ff80358af1
   ("r8169: avoid NAPI scheduling delay.") made to fix the same
   problem in the r8169 driver.  From Francois Romieu.
