Revert "drm/i915/gem: Drop relocation slowpath".
This reverts commit 7dc8f1143778 ("drm/i915/gem: Drop relocation
slowpath"). We need the slowpath relocation for taking ww-mutex
inside the page fault handler, and we will take this mutex when
pinning all objects.
We also functionally revert ef398881d27d ("drm/i915/gem: Limit
struct_mutex to eb_reserve"), as we need the struct_mutex in
the slowpath as well, and a tiny part of 003d8b9143a6 ("drm/i915/gem:
Only call eb_lookup_vma once during execbuf ioctl"). Specifically,
we make the -EAGAIN handling part of fallback to slowpath again.
With this, we have a proper working slowpath again, which
will allow us to do fault handling with WW locks held.
