drm/i915/gem: Limit struct_mutex to eb_reserve
We only need to serialise the multiple pinning during the eb_reserve
phase. Ideally this would be using the vm->mutex as an outer lock, or
using a composite global mutex (ww_mutex), but at the moment we are
using struct_mutex for the group.
Closes: https://gitlab.freedesktop.org/drm/intel/issues/1381
Fixes: 003d8b9143a6 ("drm/i915/gem: Only call eb_lookup_vma once during execbuf ioctl")
