Race condition has been noticed after warm reboot: sometimes when
port_changed notification was received, the link message didn't
have the device name. Without device name, creating team port
would fail.

Registering to the interface information change notification, so
later when device name becomes available, retry creating team port.

* [vm build] force Linux to drop cache before calling kvm

KVM need to allocate 2G memory for this build. The system memory might
be occupied by cache at the moment and doesn't have 2G chunk to give
out. Forcing Kernel to drop cache to boost the chance of getting 2G
memory.

* combine after lines

When adding a lag member dynamically after system boots up, teamd
port priv change handler could re-entrant itself and causing adding
operation to fail.

While handling PORT_CHANGE event, teamd_per_port.c port priv change
handler was called, it will then call runner_lacp to add port to lag,
the later causes IFINFO_CHANGE to be notified and calls the priv change
handler again, this re-entrance would cause runner_lacp port_added to
be called again and messes up with the previous adding sequence. Then
fails the lag member adding operation.

Prevent per port priv change handler re-entrance solves the problem.
