Shuhei Matsumoto 15040628ec bdev: Add min/max_latency_read/write/unmap_ticks into I/O statistics
Add max/min_read/write/unmap_latency_ticks into the struct
spdk_bdev_io_stat.

When initializing or resetting the instance of the struct
spdk_bdev_io_stat, initialize max to 0 and min to UINT64_MAX.

Then update max if a new value is larger than the current max,
and update min if a new value is smaller than the current min.

For the bdev_get_iostat RPC, it prints max and prints min if min is not
UINT64_MAX or 0 if min is UINT64_MAX.
