simple_stripe distribution not balanced when datafiles greater than number of I/O servers

[mtmoore]

When a request to pvfs2-cp (and potentially other tools) creates a file with a number of datafile handles greater than the number of remote I/O servers (from the perspective of the metafile handle owner) no more than 1 datafile is allocated from the local pool of I/O handles.

This occurs when a server is configured as both a metadata and I/O server and the metafile handle for a file is located on that server. After the initial datafile handle is allocated no additional datafile handles will be allocated from the local I/O server's range.

This is no longer an issue. Changes were put in place to prevent the creation of a file with more handles than I/O servers.
