[PATCH] drm/xe: Fix build without CONFIG_FAULT_INJECTION

[Rodrigo Vivi]

Ideally this header could be included without the CONFIG_FAULT_INJECTION
and it would take care itself for the includes it needs.
So, let's temporary workaround this by moving this below and including
only when CONFIG_FAULT_INJECTION is selected to avoid build breakages.

Another solution would be us including the linux/types.h as well, but
this creates unnecessary cases.
