cd9660_readdir() to return the address of the file's first data block as
the inode number instead of the address of the directory entry, but
neglected to update cd9660_vget_internal() for the new inode numbering
scheme.
Since the NFS server calls VFS_VGET (cd9660_vget()) with inode numbers
returned through VOP_READDIR (cd9660_readdir()) when servicing a READDIRPLUS
request, these two interfaces must agree on the numbering scheme; failure to
do so caused panics and/or bogus information about the entries to be returned
to clients using READDIRPLUS (Solaris, FreeBSD w/ mount -o rdirplus).
