The gk20a implementation of instance memory uses vmap()/vunmap() to map memory regions into the kernel's virtual address space. These functions may sleep, so protecting them by a spin lock is not safe. This triggers a warning if the DEBUG_ATOMIC_SLEEP Kconfig option is enabled. Fix this by using a mutex instead.
