The tm-resched-dscr self test can, in some situations, run for
several minutes before being successfully interrupted by the context
switch it needs in order to perform the test. This often seems to
occur when the test is being run in a virtual machine.
Improve the test by running it under eat_cpu(

nest_imc_refc is a reference count struct,
used to track number of active perf sessions
using the nest units.
It is preferred to access nest_imc_refc using
per-cpu pointer 'local_nest_imc_refc'. Since,
nest_imc_refc is not initialized using node_id
as array index. Patch to fix the same.
Fixes: 88
