When accel task is processed is processed in
several iterations (submit part of cryops, wait
for completion and submit next part of cryops),
sgl is initialized with offset to exclude previously
processed blocks. However there is a bug since
spdk_iov_sgl_init doesn't advance iovs, as result
when we do sgl->iov->iov_len - sgl->iov_offset,
we may get unsigned int underflow.
Fix is init sgl with 0 offset and then advance it
with offset.
Modified unit test and added an assert in code to
verify this fix.
