When no ip pim is performed subsequent pim related
configs under the interface also implicitly deleted.
The previous fix was attempting to remove from the same
list which was being integrated.
First collect the lines to remove in separate list
then at the end remove from the original lines_to_del.
commit 623af04e1c does not work properly if tries to delete
an entry from existing list which is being walked on.
