From: Jie Liu <jeff.liu@xxxxxxxxxx>

A preparation step.

For now fsync_ts transaction use the pre-calculated log reservation
size of tr_swrite.
This patch introduce a new item tr_fsyncts to mp->m_reservations
structure so that we can fetch the log reservation value for it
in a same manner to others.
