[PATCH][next] drm/i915/selftests: fix null pointer dereference on pointer data

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

In the case where data fails to be allocated the error exit path is
via label 'out' where data is dereferenced in a for-loop.  Fix this
by exiting via the label 'out_file' instead to avoid the null pointer
dereference.

Addresses-Coverity: ("Dereference after null check")
Fixes: 50d16d44cce4 ("drm/i915/selftests: Exercise context switching in parallel")
