9p: Include fsync support for 9p client
Implement the fsync in the client side by marking stat field values to 'don't touch' so that server may
interpret it as a request to guarantee that the contents of the associated file are committed to stable
storage before the Rwstat message is returned.
Without this patch, calling fsync on a 9p file results in "Invalid argument" error. Please check the attached
C program.
