Fix size on open and seek

The patch fixes the size on open bug by setting the RTEMS iop size field.

It also fixes the seek to end then write bug. There where a couple of edge
cases where the pos was being tested as equal to the length. It is not. A file
grow needed to grow the length to the position + 1. The inode not being updated
was due to the map's offset being set (updated by the write) without the map
being marked as dirty. As a result the map was not pushed to the inode on
close. Writing over a block did tag the map as dirty.
