ioengines: bump up FIO_IOOPS_VERSION

ioengines: bump up FIO_IOOPS_VERSION

For fdp backend the way ruhs are fetched has been changed.
Earlier fdp_fetch_ruhs was called once with a buffer that can store
ruhs upto FDP_MAX_RUHS. The new fdp_fetch_ruhs is called twice. The
first call doesn't have any buffer for ruhs, and is only to get the
number of ruhs reported by the device. The second call has the buffer
that can store all the ruhs.

This impacts any external ioengines, so bump up FIO_IOOPS_VERSION.

Fixes: commit 56d12245 (dataplacement: update ruh info initialization)
