Thanks Paul, I've done that now

It looks like `execute_attr_map_slot(attrMap, in_slot, out_slot)` always
returns `out_slot`, so assigning the return value to `out_slot` is a no-op.

I see a couple of such no-op assignments in the codebase - we could remove
them if we think it improves clarity?

I don't have any objections to execute_attr_map_slot's interface - it
seems conventional for functions that copy/transform a data structure
into a caller-passed buffer to also return a pointer to the buffer,
e.g. ExecCopySlot, strcpy(3), realpath(3)
