Quan Nguyen 6e657a5515 ipmi: ssif_bmc: Fix new request loss when bmc ready for a response 
[ Upstream commit 83d8c79aa9 ]

Cosmo found that when there is a new request comes in while BMC is
ready for a response, the complete_response(), which is called to
complete the pending response, would accidentally clear out that new
request and force ssif_bmc to move back to abort state again.

This commit is to address that issue.
