drivers/ata/libata: Move dereference after NULL test
In each case, if the NULL test on qc is needed, then the derefernce
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>
