drm/i915: Remove unnecessary null check in execlists_context_unqueue
commit 53292cdb06
("drm/i915: Workaround
to avoid lite restore with HEAD==TAIL") added a check for req0 != null
which is unnecessary.
The only way req0 could be null is if the list was empty, and this is
already addressed at the beginning of execlists_context_unqueue().
