bsrange doesn't accept separate read,write values

[Dave Engberg <dengberg@evernote.com>]

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

Here's my attempt at a patch for this:

            strncpy(tmp, ptr, sizeof(tmp) - 1);

+         // Handle bsrange with separate read,write values:
+         p1 = strchr(tmp, ',');
+         if (p1) {
+           *p1 = '\0';

            p1 = strchr(tmp, '-');
            if (!p1) {
                p1 = strchr(tmp, ':');
