[PATCH v2] drm/nouveau: Improve variable names in nouveau_sched_init()

[Philipp Stanner]

nouveau_sched_init() uses the function drm_sched_init(). The latter
function has parameters called "hang_limit" and "timeout" in its API
documentation.

nouveau_sched_init(), however, defines a variable called
"job_hang_limit" which is passed to drm_sched_init()'s "timeout"
parameter. The actual "hang_limit" parameter is directly set to 0.

Rename "job_hang_limit" to "timeout".

- Remove variable "hang_limit". (Danilo)
