[LTP] [PATCH] io_control01: Initialise the io_stats start structure

[Ashwin Dayanand Kamat]

struct io_stats start structure is a locally declared structure
which when not initialised can be filled with junk values in some platforms
like arm. These values are later compared and hence it leads to failure on
photon arm platform. Fix is to memset the structure.
