ethernet: s2io: disable napi when start nic failed in s2io_card_up()

[ Upstream commit 0348c1ab980c1d43fb37b758d4b760990c066cb5 ]

When failed to start nic or add interrupt service routine in
s2io_card_up() for opening device, napi isn't disabled. When open
s2io device next time, it will trigger a BUG_ON()in napi_enable().
Compile tested only.

Fixes: 5f490c968056 ("S2io: Fixed synchronization between scheduling of napi with card reset and close")
