When flushing queued messages in run-to-completion mode,
smi_event_handler() is recursively called.
flush_messages()
smi_event_handler()
handle_transaction_done()
deliver_recv_msg()
ipmi_smi_msg_received()
smi_recv_tasklet()
sender()
flush_messages()
smi_event_handler()
...
The depth of the recursive call depends on the number of queued
messages, so it can cause a stack overflow if many messages have
been queued.
To solve this problem, this patch removes flush_messages()
from sender()@ipmi_si_intf.c. Instead, add flush_messages() to
caller side of sender() if needed. Additionally, to implement this,
add new handler flush_messages to struct ipmi_smi_handlers.
