avoid the double free
Bug File: sys/netpfil/ipfw/dn_aqm_pie.c
In function aqm_pie_enqueue, m is freed via m_freem(m) at line 545.
But the freed m is freed again by FREE_PKT(m) at line 561.
My patch returns the error right away when m_tag_alloc() allocate memory
failed, rather than continues to free the m again.
