[PATCH v2 1/5] drm/panthor: Preserve the result returned by panthor_fw_resume()

[Boris Brezillon]

WARN() will return true if the condition is true, false otherwise.
If we store the return of drm_WARN_ON() in ret, we lose the actual
error code.

v2:
- Add R-b

Fixes: 5fe909cae118 ("drm/panthor: Add the device logical block")
