Laszlo Ersek ffbb5ae3ba MdeModulePkg: RegularExpressionDxe: support free(NULL)
The ISO C standard says about free(),

  If ptr is a null pointer, no action occurs.

This is not true of the FreePool() interface of the MemoryAllocationLib
class:

  Buffer must have been allocated on a previous call to the pool
  allocation services of the Memory Allocation Library. [...] If Buffer
  was not allocated with a pool allocation function in the Memory
  Allocation Library, then ASSERT().

Therefore we must not forward the argument of free() to FreePool() without
checking.
