[PATCH] IB/hfi1: Add missing break in switch statement

[Gustavo A. R. Silva]

Fix the following warning by adding a missing break:

drivers/infiniband/hw/hfi1/tid_rdma.c: In function 
‘hfi1_tid_rdma_wqe_interlock’:
drivers/infiniband/hw/hfi1/tid_rdma.c:3251:3: warning: this statement may fall 
through [-Wimplicit-fallthrough=]
   switch (prev->wr.opcode) {
   ^~~~~~
drivers/infiniband/hw/hfi1/tid_rdma.c:3259:2: note: here
  case IB_WR_RDMA_READ:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

Fixes: c6c231175ccd ("IB/hfi1: Add interlock between TID RDMA WRITE and other 
requests")
