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].
