Remove the WARN_ON(ce->state) inside the static function only called
when ce->state == NULL and downgrade the w/a batch setup warning into a
developer only mode (GEM_WARN_ON).
v2: Move the deferred alloc guard into the callee, eliminating the need
for the WARN_ON:
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-1 (-1)
Function old new delta
execlists_context_pin 1819 1818 -1
