pco: Fix pco_last_igrp returning the first element instead of the last

Browse source 
Because of a previous refactor, pco_last_igrp was incorrectly changed to return
the first entry in a linked list instead of the last. Update pco_last_igrp to
return the last entry in a linked list.

The following CTS tests now pass:
dEQP-GLES3.functional.shaders.switch.conditional_fall_through_2_dynamic_fragment
dEQP-GLES3.functional.shaders.switch.conditional_fall_through_dynamic_fragment
dEQP-GLES3.functional.shaders.switch.conditional_fall_through_uniform_fragment

Fixes: 719ece42c0 ("pco: Switch back to util/list")
