[PATCH] drm/vmwgfx: Fix some scheduling in atomic bugs

[Dan Carpenter]

The vmw_gmrid_man_get_node() function calls vmw_host_printf() while
holding a spinlock so these functions need to be atomic.  Generally,
no one expects printf() functions to sleep.

Fixes: cfdc3458db8a ("drm/vmwgfx: Be a lot more flexible with MOB limits")
