[PATCH 17/17] btrfs-progs: replace strtok_r with strsep

[Eric Sandeen <sandeen@redhat.com>]

The coverity had a false positive complaining that save_ptr
is uninitialized in the call to strtok_r.

We could initialize it, but Zach points out that just using
strsep is a lot simpler if there's only one delimiter,
so just switch to that.
