When initiating the io_u strcture from FIO, always
set the engine_data to NULL first as the io_u structure
is just malloced from FIO without specifically setting
to zero.
In the io_u free path, the engine_data field is checked
whether to NULL or not. To avoid mischeck issue, explicitly
set the engine_data to NULL at the beginning of the io_u
init path.
