Release an open file.
`release` is called when there are no more references to an open file: all file descriptors
are closed and all memory mappings are unmapped. For every `open` call there will be
exactly one release call. The filesystem may reply with an error, but error values are not
returned to close() or munmap() which triggered the release. `fh` will contain the value
set by the open method. `flags` will contain the same flags as for `open`.
