sky2: Avoid down and up during sky2_reset

Browse source

Rewrite sky2_reset to work with interrupts disabled and
 avoid freeing and reallocing memory.

The old code used sky2_down and sky2_up to implement sky2_reset,
 which meant interrupts could not be disabled, and the transmit and
 receive ring buffers would be free'd and reallocated.

To avoid the interrupt handler waking the transmit queue while
 we're doing a reset, it's better to have interrupts and NAPI
 polls disabled.

Note: Modified Mike's patch to do IRQ disable in sky2_down before
 calling sky2_hw_down - Stephen
