sky2: avoid pci write posting after disabling irqs
In sky2_change_mtu setting B0_IMSK to 0 may be delayed due to PCI write posting which could result in irqs being still active when synchronize_irq is called. Since we are not prepared to handle any further irqs after synchronize_irq (our resources are freed after that) force the write by a consecutive read from the same register. Similar situation in sky2_all_down: Here we disabled irqs by a write to B0_IMSK but did not ensure that this write took place before synchronize_irq. Fix that too.
