Ticket #346 - Fixing memory leaks

Description:
There was a leak in attrlist_replace/attrlist_replace_with_flags
when attr_replace failed to replace the attribute values.

commit 708a56b8d524131362e2d71b7fbc2eb257075e14 for Ticket #47834
tried to fix it, but it was wrong and introduced a double free.
This patch fixes it so that ...
If attr_replace fails and if to be replaced Slapi_Attr is newly
created in attrlist_replace//attrlist_replace_with_flags, the
Slapi_Attr is removed from the attrlist (alist) and Slapi_Attr
is freed.  Otherwise, values and Slapi_Attr are not freed since
Slapi_Attr is just pointing the attribute in the attrlist and
values are consumed in attr_replace.
