Fix bsrange read,write value option pairs

The 'bs' and 'bssplit' configuration variables accept separate numbers
for read and write operations if you separate them with a comma. For
example: bssplit=1k/39:8k/50:64k/11,1k/29:8k/50:64k/21

The documentation for 'bsrange' says it works the same way, but if I try
to specify two ranges with a comma, I get an error when I run the app.
E.g. if I put this line in the configuration file: bsrange=1k-16k,2k-32k

I get this error output:

fio: pid=26861, err=22/file:engines/sync.c:62, func=xfer, error=Invalid argument

This patch fixes it.
