drivers/net: Move a dereference below a NULL test
If the NULL test is necessary, then the dereference should be moved below
the NULL test.
The semantic patch that makes this change is as follows:

type T;
expression E,E1;
identifier i,fld;
statement S;
@@
- T i = E->fld;
+ T i;
... when != E=E1
when != i
if (E == NULL||...) S
+ i = E->fld;
