Staging: sxg: Fix interface bug not working after open is called second time.

Fix the problem of the interface not working after a sequence of up-down-up
events. The problem was observed only on systems where the card was using MSI-X
interrupts. On the second time open, the driver did not request MSI-X vector
but was trying to use normal interrupts.
