Navdeep Parhar fddd4f6273 Plug leak in m_unshare. 
m_unshare passes on the source mbuf's flags as-is to m_getcl and this
results in a leak if the flags include M_NOFREE.  The fix is to clear
the bits not listed in M_COPYALL before calling m_getcl.  M_RDONLY
should probably be filtered out too but that's outside the scope of this
fix.

Add assertions in the zone_mbuf and zone_pack ctors to catch similar
bugs.

Update netmap_get_mbuf to not pass M_NOFREE to m_getcl.  It's not clear
what the original code was trying to do but it's likely incorrect.
Updated code is no different functionally but it avoids the newly added
assertions.
