Fix for Adaptec Starfire resource handling

[Ion Badulescu]

Hi,

The starfire driver in 2.4.0 (and 2.4.0-ac8) forgets to release its MMIO
region when the module is unloaded, which makes it impossible to load it a
second time. The attached patch fixed this problem; I tested it here on a
2-port card.

Please apply.

Thanks,
Ion
