nommu: yield CPU while disposing VM
commit 04c3496152394d17e3bc2316f9731ee3e8a026bc upstream.
Depending on processor speed, page size, and the amount of memory a
process is allowed to amass, cleanup of a large VM may freeze the system
for many seconds. This can result in a watchdog timeout.
Make sure other tasks receive some service when cleaning up large VMs.
