lightnvm: pblk: fix changing GC group list for a line
pblk_line_gc_list seems to had a bug since the introduction of pblk in getting GC list for a line. In b20ba1bc7 while redesigning the GC algorithm, the naming for the GC thresholds was altered, but the values for high_thrs and mid_thrs were not. The result is that when moving to the GC lists, the mid threshold is never evaluated.
