Subject: mei: make device disabled on stop unconditionally
From: Alexander Usyskin <alexander.usyskin@xxxxxxxxx>
commit 6c15a8516b8118eb19a59fd0bd22df41b9101c32 upstream.
Set the internal device state to to disabled after hardware reset in stop flow.
This will cover cases when driver was not brought to disabled state because of
an error and in stop flow we wish not to retry the reset.
