x86: make pcpu_chunk_addr_search() matching stricter

The @addr passed into pcpu_chunk_addr_search() is unit0 based address
and thus should be matched inside unit0 area.  Currently, when it uses
chunk size when determining whether the address falls in the first
chunk.  Addresses in unitN where N>0 shouldn't be passed in anyway, so
this doesn't cause any malfunction but fix it for consistency.

[ Impact: mostly cleanup ]
