isa-skelton: Remove a wrong netif_wake_queue() call

The netif_wake_queue() is called correctly (i.e. only on !txfull
condition) from net_tx().  So Unconditional call to the
netif_wake_queue() here is wrong.  This might cause calling of
start_xmit routine on txfull state and trigger tx-ring overflow.

This fix is ported from commit 662a96bd
("tc35815: Remove a wrong netif_wake_queue() call which triggers BUG_ON").
