kernel - Fix excessive mbuf use in nfs_realign()
* nfs_realign() was calling m_copyback() which itself uses the deprecated
m_getclr(), and m_getclr() only allocates non-cluster mbufs.
This caused nfs_realign() to use an excessive number of mbufs and can
exhaust the mbuf pool on systems with small amounts of memory.
