RDMA/cxgb4: Configure 0B MRs to match HW implementation
0B MRs need some tweaks to work correctly with HW. When writing the
TPTE, if the MR length is zero we now:
1) turn off all permissions
2) set the length to -1
While functionality/capabilities of the MR are the same with these
changes, it resolves a dapltest 0B RDMA Read test failure. Based on
original work by Steve Wise <swise@opengridcomputing.com>.
