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.
