IB/hfi1: Remove redundant variable rcd

The variable rcd is being assigned a value from a calculation however the
variable is never read, so this redundant variable can be removed.

Cleans up the following clang-analyzer warning:

drivers/infiniband/hw/hfi1/affinity.c:986:3: warning: Value stored to
'rcd' is never read [clang-analyzer-deadcode.DeadStores].
