set relay file can not be read by pread(2)
I found that relay files can be read by pread(2). I fix it,
for relay files are not capable of seeking.

as it will break any existing apps which are using pread() against relayfs
files. This presently works OK as long as the offset is zero, so there may be
such apps out there.
