we can't open container files by device/inode number pair anymore. Replace the CODA_OPEN upcall with CODA_OPEN_BY_FD, where venus returns an open file descriptor for the container file. We can then grab a reference on the vnode coda_psdev.c:vc_nb_write and use this vnode for further accesses to the container file.
