Add support for FOPEN_NOFLUSH flag
Allow requesting from kernel to avoid flush on close at file open
time. If kernel does not support FOPEN_NOFLUSH flag, the request
will be ignored.
For passthrough_hp example, request to avoid flush on close when
writeback cache is disabled and file is opened O_RDONLY.
