net/e1000: fix crash on Tx done clean up

As tx mbuf is not set for some advanced descriptors, if there is no
mbuf checking before rte_pktmbuf_free_seg() function be called on
the process of tx done clean up, that will cause a segfault. So add
a NULL pointer check to fix it.

Bugzilla ID: 501
Fixes: 8d907d2b79f7 ("net/igb: free consumed Tx buffers on demand")
