Subject: [PATCH] drm: nouveau: lsfw: cleanup coccinelle warning

From: Wang Qing <wangqing@...o.com>

odd_ptr_err.cocci has complained about this warning for a long time:
lsfw.c:194:5-11: inconsistent IS_ERR and PTR_ERR on line 195.

Although there is no actual impact, it can improve scanning efficiency.
