Subject: [PATCH] RDMA/hfi1: remove redundant assignment to pointer ppd

Pointer ppd is being assigned a value in a for-loop however it
is never read. The assignment is redundant and can be removed.
Cleans up clang scan build warning:

drivers/infiniband/hw/hfi1/init.c:1030:3: warning: Value stored
to 'ppd' is never read [deadcode.DeadStores]
