[LTP] [PATCH 2/2] cpuset_memory: Fix race in multinode subtests

[Martin Doucha]

In two subtests, memory allocation races against a change of the allowed
cpuset nodes list. This causes random failures. Add the missing sleep
to ensure that memory allocation completes before the allowed nodes
get changed.
