The memory allocation function ACPI_ALLOCATE_ZEROED does not
guarantee a successful allocation, but the subsequent code
directly dereferences the pointer that receives it, which may
lead to null pointer dereference. To fix this issue, a null
pointer check should be added. If it is null, return exception
code AE_NO_MEMORY.
