Jim Harris 12d191ec12 Add handling for controller fatal status (csts.cfs). ...

On any I/O timeout, check for csts.cfs==1.  If set, the controller
is reporting fatal status and we reset the controller immediately,
rather than trying to abort the timed out command.

This changeset also includes deferring the controller start portion
of the reset to a separate task.  This ensures we are always performing
a controller start operation from a consistent context.
