Remove gem_mmap__{cpu,gtt,wc} return value MAP_FAILED asserts

Browse Source 
gem_mmap__{cpu,gtt,wc} never return MAP_FAILED, it gets converted to
NULL internally. So don't go asserting that the returned value is
not MAP_FAILED.

Done with coccinelle:
@@
type T;
identifier I;
@@
(
 I = gem_mmap__gtt(...);
|
 I = gem_mmap__cpu(...);
|
 I = gem_mmap__wc(...);
)
 ...
(
- igt_assert(I != MAP_FAILED);
+ igt_assert(I);
|
- igt_assert(I && I != MAP_FAILED);
+ igt_assert(I);
|
- igt_assert(I != (T *) MAP_FAILED);
+ igt_assert(I);
|
- igt_assert(I != NULL);
+ igt_assert(I);
)
