b939ca9370 mcctrl: refactor prepare_image into new generic ikc send&wait 
Many ikc messages expecting a reply use wait_event_interruptible
incorrectly, freeing memory that could still be used on the other side.

This commit implements a generic ikc send and wait helper that helps
with memory management and ownership properly:
 - if the message succeeds and a reply comes back normally, the memory
is freed by the caller as usual
 - if the wait fails (signal before the reply comes or timeout) then the
memory is set as owner by ikc and will be free when the reply comes back
later
 - if the reply never comes, the memory is freed at shutdown when
destroying ikc channels
