bitbake: fetch2: Add NFS Stale file exception handling
- In some cases the file descriptor is held by nfs client and none of os.path.* is catching that, it could mean that error is not doled out because client has cached the stat info. In this case we are out of luck. Needed to catch IOError, which would be causing the Stale error. - In download method, update_stamp is invoked md5sum validation which is found to be throwing Stale errors. - Added error handling to fix the stale errors.
