zram: correctly handle all next_arg() cases
When supplied buffer does not have assignment sign next_arg() sets `val`
pointer to NULL, so we cannot dereference it. Add a NULL pointer test to
handle `param` case, in addition to `*val` test, which handles cases when
param has no value assigned to it: `param=`.
