[PATCH][next] drm/xe: Fix uninitialized pointer def

[Colin Ian King <colin.i.king@gmail.com>]

In the case where a set of checks on xe->info.platform don't assign
a value to pointer def the pointer remains uninitialized and hence
can fail the following !def check. Fix this be ensuring pointer
def is initialized to NULL.
