tg3: Fix single MSI-X vector coalescing
The interrupt coalescing setup code used the TG3_FLG2_USING_MSIX flag to
determine whether or not to configure the rx coalescing parameters.
This is incorrect for the single MSI-X vector case. This patch changes
the code to look at the TG3_FLG3_ENABLE_RSS instead.
