ipmi: Add a function to (re)initialise a message without allocation
Currently the only functions we have for initialising ipmi messages
with the correct values also allocate memory for the message. In some
cases we want to reuse previously allocated messages to avoid
continually freeing/allocating memory.
This patch introduces a function which (re)initialises a previously
allocated message and converts existing instances of this behaviour
over to the new function.
