MdePkg/UefiDevicePathLib: Fix RAM Disk Device Path To Text Issue

Perform Left Shift 32 bits of a 32-bit StartAddr[1] and EndingAddr[1]
instead of Right Shift when displaying 64-bit Start and End Address Value.

StartAddr[1] and EndingAddr[1] are already a 32-bit value and it should
perform left shift 32-bit to generate a complete 64-bit value along with
StartAddr[0] and EndingAddr[0] respectively.
