It does not impact R3.2. Verified in my testbed

FillCpuInfo fails when files under /proc are not retrievable
sometimes. Including checks in base/cpuinfo.cc so that we
return error and deal with error messages for all calls that
open /proc files. If error occurs, we log a message and dont
send UVE.The tasktriggers should return TRUE even if FillCpuInfo
fails otherwise, the task will get recycled.
