In my test, @to has a fraglist, but skb_tailroom(to) is not 0!
The test is about tipc, the function tipc_buf_append will merge 3 skbs
to one:
packet 1: len = 1420 skb_tailroom = 190
packet 2: len = 1420
packet 2 will be add to 1'

When try to merge several skbs to prior one, if the frag_list is
used and the the last one is a small packet, once the condition
"len <= skb_tailroom(to)" is satisfied, we will get a wrong
packet!
This patch just check frag_lists before the condtion to prevent
this from happeni
