Two fixes for the ROMIO io module:

 * Don't call PMPI_* anything from our module code; that's terribly
   bad form (and disallowed!).  Instead, do the proper back-end stuff
   to reset the error handler on the file handle.
 * If we've already started to MPI_Finalize, then just give up and
   don't actually perform all the file closing actions (because
   ROMIO's file close calls MPI_Barrier, which will obviously fail if
   MPI_Finalize has already been invoked).  Bad user behavior should
   be punished (by leaking resources, not closing the file properly,
   etc.).

Update hwloc from 1.5.1 to 1.5.2.  Re-enable hwloc PCI support by
default, since it will now use libpciaccess (if available).

Add missing unlocks.  Fixes CID 967022 (which covers the unlock on
line 627; there's probably another CID for the unlock added on line
537).
