spi/orion: Drop unnecessary null test

list_for_each_entry binds its first argument to a non-null value, and thus
any null test on the value of that argument is superfluous.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

iterator I;
expression x,E;
@@

I(x,...) { <...
- (x != NULL) &&
  E
  ...> }
// </smpl>
