IB/mthca: Always fill MTTs from CPU
Speed up memory registration by filling in MTTs directly when the CPU can write directly to the whole table (all mem-free cards, and to Tavor mode on 64-bit systems with the patch I posted earlier). This reduces the number of FW commands needed to register an MR by at least a factor of 2 and speeds up memory registration significantly. Signed-off-by: Michael S.
