[PATCH] gpu: drm: nouveau: nvkm: nv50: Replace mdelay() with msleep() in nv50_sensor_setup()

[Jia-Ju Bai]

nv50_sensor_setup() is never called in atomic context.
It calls mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().

This is found by a static analysis tool named DCNS written by myself.
