ACPICA: Avoid undefined behavior: applying zero offset to null pointer

ACPICA commit 770653e3ba67c30a629ca7d12e352d83c2541b1e

Before this change we see the following UBSAN stack trace in Fuchsia:

Add a simple check that avoids incrementing a pointer by zero, but otherwise behaves as before. Note that our findings are against ACPICA 20221020, but the same code exists on master.
