btrfs-progs: initialize save_ptr prior to strtok_r

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

Turns out that under the covers glibc was doing enough
to confuse the checker about what was being called.

Just to keep the noise down, do a harmless initialization,
with a comment as to why.
