net_sched: check NULL in tcf_block_put()
Callers of tcf_block_put() could pass NULL so
we can't use block->q before checking if block is
NULL or not.
tcf_block_put_ext() callers are fine, it is always
non-NULL.
Fixes: 8c4083b30e56 ("net: sched: add block bind/unbind notif. and extended block_get/put")
