Summary: Can't migrate if remote shm seg open - reop_export_path erro

Initial Comment:
If a process attaches to a remote shm segment then tries to migrate then we get "reop_export_path: Can't export unlinked file /SYSV7a6d2001 (deleted)" and the migration fails.

Whoops, poor coordination - just checked in a fix that does more or less
what Rogers patch below does.  Works for me.

Attached patch for kernel tests path for shared memory before trying to
export as a file.
File Added: cluster_ssi_vproc_reopen.c.patch

reop_export_path is testing for deleted file before shared memory seg. 
Code in reop_import_path looks for shared memory (in fact any file called
/SYSVxxxxxxxx) first.   Maybe fix by reordering code in reop_export_path.
