MdeModulePkg/PiSmmCore: Fix an assert issue in pool free

Browse Source 
Following check-in caused this issue:
  2930ef9809976ce693d1d377851344c3b06bd926

This issue is caused by assigning incorrect value to PoolHdr.Size
if the requested size is more than MAX_POOL_SIZE, because the SMM
core will actually allocate page memory instead of pool memory in
this situation.
