fusefrontend: doWrite: report readFileID errors as I/O error
It used to be reported as "function not implemented", accompanied
with this log output:
go-fuse: can't convert error type: ParseHeader: header is all-zero. Header hexdump: 000000000000000000000000000000000000
Now we report EIO and log this:
doWrite 1372183: corrupt header: ParseHeader: header is all-zero. Header hexdump: 000000000000000000000000000000000000
