CID 1488814:  Uninitialized variables  (UNINIT)

Commit c66ea98 introduced an issue after static analysis on merge.
Because every APIC is associated with a CPU, this did not result in
any issues at runtime but should be fixed/cleaned up.  Now, the path
name is initialized to null.

Fixes: Coverity CID 1488814, commit c66ea98
TEST=Built on brya
