Initialize a pointer in split_init_cmd() to avoid gcc warnings

gcc -Wall warns about uninitialized variables (-Wmaybe-uninitialized), and -Werror makes it fatal. This change allows the build to succeed by NULL'ifying the pointer passed to strtok_r(). Note that strtok_r(3) anyway ignores a non-NULL arg3 pointer on the 1st call with non-NULL arg1 string.
