ipmi: Don't call receive handler in the panic context
Received handlers defined as ipmi_recv_hndl member of struct ipmi_user_hndl can take a spinlock. This means that if the kernel panics while holding the lock, a deadlock may happen on the lock while flushing queued messages in the panic context. Calling the receive handler doesn't make much meanings in the panic context, simply skip it to avoid possible deadlocks.
