MdeModulePkg/ReportStatusCodeRouter: Update RSC Data on reallocation 

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2670

The RSC router data buffer may be reallocated when the buffer is nearing
exhaustion (7/8 portion of the buffer used).

While several pointers are updated to point to the newly allocated buffer,
the RscData is not updated. This commit updates the RSC data pointer
to the same offset in the reallocated data buffer.
