file-posix: account discard operations
This will help to identify how many of the user-issued discard operations (accounted on a device level) have actually suceeded down on the host file (even though the numbers will not be exactly the same if non-raw format driver is used (e.g. qcow2 sending metadata discards)). Note that these numbers will not include discards triggered by write-zeroes + MAY_UNMAP calls.
