The current logic in storage_migrate.ml for mirror failure check is specific to tapdisk, hence multiplex it. `pre_deactivate_hook` also has something similar to check for mirror failure, so do something similar there. Signed-off-by: Vincent Liu <[email protected]>

Previously this was deleted in commit 1fe6389 as it was not multiplexed, but looks like we still need to keep it in storage_mux because sm-cli needs to make rpc calls to storage_mux when trying to list all the mirrors to make it work properly, due to the fact that the sr plugins are stored in the address space of the xapi process. There are other invocations in sm-cli such as `Storage_migrate.start` which may have similar problems. But I have left them alone as I don't any reasonable way of calling them from the cli.
