* libc/libio.c (rtems_libio_allocate): Make sure size and offset
	fields are cleared on each file open.  Before this field was cleared,
	this resulted in the value from the last time that IOP was used
	being still in place.  Discovered by  Andrew Bythell
	<abythell@nortelnetworks.com>.
	* libc/open.c: Remove redundant setting of iop->offset.
