drm: remove redundant drm_file->uid
Each DRM file-context caches the EUID of the process that opened the file.
It is used exclusively for debugging purposes in /proc/dri/ and friends.
Note, however, that we can already fetch the EUID from
priv->pid->task->creds. The pointer-chasing will not hurt us, since it is
only about debugging, anyway.
Since we already are in an rcu-read-side, we can use __task_cred() rather
than task_cred_xxx().
