The function returns -ENOBUFS when handling OCF_WRITE_FLUSH requests
on a disk with a size which its lower 32-bits are zeros. Zeroing the
request buffer length occurs when creating a new ocf_io and assigning
a 64-bit value to a 32-bit value in vbdev_ocf.c:io_handle.
This patch fixes the condition to check if the request have a payload
(data->iovs) before checking for the size limitation.
