Brian Behlendorf fc87e269e2 Initialize vr_last_txg for rebuild
Only call txg_wait_synced() when rebuild IOs were issued for this
metaslab.  This is a small optimization since in practice the first
metaslab is very likely to have allocations and cause vr_last_txg
to be initialized.  After this point when processing empty metaslabs
txg_wait_synced() is called but with an already committed txg so it
will not wait.  Still it's better not to call txg_wait_synced() at
all when it's not needed.
