QcomModulePkg: Validate ddr header version before validating its fields

Do not check validity of ddr rank and channel before checking
ddr header version as these fields might not be present with older
ddr header version and we end up failing updating DT and that
could result in bootup failure.

Fix it by moving the ddr rank/channel validity check after checking
its ddr header version validity.
