kernel: drop unneeded modification of mtd_add_partition function
In old days mtd_add_partition was checking for partitions overlapping which was breaking our splitting feature. We had to modify this function by adding an extra bool dup_check parameter. Upstream commit: 3a434f66e6da ("mtd: part: Remove partition overlap checks") removed that check so we don't need our modification anymore.
