[Intel-gfx] [PATCH] drm/i915: Drop inspection of execbuf flags during evict

[Joonas Lahtinen]

> With the goal of removing the serialisation from around execbuf, we will
> no longer have the privilege of there being a single execbuf in flight
> at any time and so will only be able to inspect the user's flags within
> the carefully controlled execbuf context. i915_gem_evict_for_node() is
> the only user outside of execbuf that currently peeks at the flag to
> convert an overlapping softpinned request from ENOSPC to EINVAL. Retract
> this nicety and only report ENOSPC if the location is in current use,
> either due to this execbuf or another.
