block: Consistently call bdrv_activate() outside coroutine

Browse source 
Migration code can call bdrv_activate() in coroutine context, whereas
other callers call it outside of coroutines. As it calls other code that
is not supposed to run in coroutines, standardise on running outside of
coroutines.

This adds a no_co_wrapper to switch to the main loop before calling
bdrv_activate().
