Fix IPMI SEL reservations and cancellations

Per the IPMI Spec, the SEL must be reserved to
   Delete an entry
   Clear the SEL
   Get a partial entry
   Add a partial entry

The current SEL reservation must be cancelled when
   A SEL entry is added
   A SEL entry is deleted
   The SEL is cleared
   The device is reset
   A new reservation is requested

This change adds a reservation status to track when a reservation
is active and a method to cancel the current reservation, and it
uses that to cancel the reservation in the Delete, Clear, and Add
SEL methods.
