[PULL 11/22] migration: I messed state_pending_exact/estimate

[Xxx Xx <quintela@xxxxxxxxxx>]

From: Juan Quintela <quintela@xxxxxxxxxx>

I called the helper function from the wrong top level function.

This code was introduced in:

commit c8df4a7aeffcb46020f610526eea621fa5b0cd47
Author: Juan Quintela <quintela@xxxxxxxxxx>

    migration: Split save_live_pending() into state_pending_*

    We split the function into to:

    - state_pending_estimate: We estimate the remaining state size without
      stopping the machine.

    - state pending_exact: We calculate the exact amount of remaining
      state.

Thanks to Avihai Horon <avihaih@xxxxxxxxxx> for finding it.

Fixes:c8df4a7aeffcb46020f610526eea621fa5b0cd47

When we introduced that patch, we enden calling

state_pending_estimate() helper from qemu_savevm_statepending_exact()
and
state_pending_exact() helper from qemu_savevm_statepending_estimate()

This patch fixes it.
