pipeline: Fix the layer index used when pruning layers

Browse source 
When pruning a pipeline to a set number of layers it records the index
of the first layer after the given number of layers have been found.
This is stored in a variable called 'first_index_to_prune' implying
that this layer should be included in the layers to be pruned. However
the subsequent if-statement was only pruning layers with an index
greater than the recorded index so it would presumably only prune the
following layers. This patch fixes it to use '>=' instead.
