btrfs-progs: utils: Fix NULL pointer derefernces in string_is_numerical
In get_running_kernel_version() function, we directly pass return
pointer from strtok_r() to string_is_numerical().
Return pointer from strok_r() can be NULL, but string_is_numerical()
can't handle it and will cause NULL pointer derefernces.
Fix it by check if it's a NULL pointer first.
