UefiCpuPkg/PiSmmCpuDxeSmm: Fix SMRAM memory leak during S3 resume
SyncContext of SMM_DISPATCHER_MP_SYNC_DATA was dynamically allocated from
SMRAM. The memory was not freed before reallocation in S3 resume path.
This could lead to:
1. Memory leak in SMRAM.
2. Potential S3 resume failure after repeated S3 tests due to SMRAM
exhaustion.
This change releases the SyncContext memory before reallocating it
