staging/rdma/hfi1: Correctly limit VLs against SDMA engines
Correctly reduce the number of VLs when limited by the number
of SDMA engines.
The hardware has multiple egress mechanisms, SDMA and pio, and multiples
of those. These mechanisms are chosen using the VL (8)
The fix corrects a panic issue with one of the platforms that doesn't have
enough SDMA (4) mechanisms for the typical number of VLs.
