OvmfPkg/AcpiPlatformDxe: fix spurious uninitialized var warning

Commit 4275f38507a4 ("OvmfPkg/AcpiPlatformDxe: alloc blobs from 64-bit
space unless restricted") introduced a variable which is [incorrectly]
identified by GCC as being potentially uninitialized. So let's just set
it to NULL before use.
