drivers/message: move dereference after NULL test
If the NULL test on dev->i2o_dev or i2o_dev is needed, then the dereference
should be after the NULL test.
A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@match exists@
expression x, E;
identifier fld;
@@
* x->fld
... when != \(x = E\|&x\)
* x == NULL
// </smpl>
