reduceErrs to handle context.Canceled errors (#13670)
With this change, reduceErrs will group all errors due to 
context cancelation as the same.

e.g, Following are errors due to context cancelation seen 
from 3 remote disks. Their error values are different but 
they are all caused due to the same context cancelation.
