drm/msm/adreno: Fix error return if missing firmware-name

BugLink: https://bugs.launchpad.net/bugs/2086138

[ Upstream commit 624ab9cde26a9f150b4fd268b0f3dae3184dc40c ]

-ENODEV is used to signify that there is no zap shader for the platform,
and the CPU can directly take the GPU out of secure mode.  We want to
use this return code when there is no zap-shader node.  But not when
there is, but without a firmware-name property.  This case we want to
treat as-if the needed fw is not found.
