[PATCH] Initialize strtok_r's saveptr to NULL

[Manish Goregaokar <manish@mozilla.com>]

Accidentally sent this directly to palves instead of to the list.


In the review of the previous patch it was mentioned that we shouldn't
need to initialize this,
but it seems like elsewhere in the codebase we initialize the saveptr
of strtok_r to NULL too.


----

This fixes a build warning.
