RPC_IFDEBUG() is used in only two places. In one the user of the definition is guarded by ifdeffery, in the second one it's implied due to dprintk() usage. Kill the macro and move the ifdeffery to the regular condition with the variable defined inside, while in the second case add the same conditional and move the respective code there.
