drm/i915/selftests: fix null pointer dereference on pointer data

Browse Source 
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: 50d16d44cc ("drm/i915/selftests: Exercise context switching in parallel")
