Remove the special treatment of non-blocking mode in
xdrrec_eof(). This change broke seriously reading serialized
xdr-records. A end of a request could sometimes not
be recognized and the answer to the client did fail.

Return always FALSE in set_input_fragment() for non-blocking
mode. Since this was not used in FreeBSD, I omitted it at the
first time. Now we use this function and we should always
return FALSE for it.
