libflash/ipmi-hiomap: Remove unused close handling

[ Upstream commit 6d8bd2d ]

Issuing a HIOMAP_C_CLOSE is not required by the protocol specification,
rather a close can be implicit in a subsequent
CREATE_{READ,WRITE}_WINDOW request. The implicit close provides an
opportunity to reduce LPC traffic and the implementation takes up that
optimisation, so remove the case from the IPMI callback handler.
