mdm9615:Fix for incorrect dsp partition name

The postition of the dsp2 partition has changed in newer builds
pushing it beyond the range of modem_partition_count used by LK.
This causes the partition name to get stored incorrectly causing
the recovery code to fail.Updated the value of this variable.
