Currently the SmmIsBufferOutsideSmmValid() function in SmmMemLib.c will
ASSERT in certain conditions. Since this function is a "test" function,
it should not be making decisions on how to handle a failure.
Handling a failure should be left to the caller.

This patch is to remove ASSERT(FALSE) at line 178 of SmmMemLib.c.
