NumPages variable was introduced in commit 66c548be509d. In this commit
we allocate an intermediate buffer when SEV is enabled. The 'BounceBuffer'
variable points to the intermediate buffer pointer and NumPages variables
stores the number of pages. Later in the code, 'BounceBuffer' variable is
checked to see if we need to free the intermediate buffers. The code looks
correct, suppress the warning.
