[PATCH 5/6] migration: Fix cache_init()'s "Failed to allocate" error messages

[Markus Armbruster]

cache_init() attempts to handle allocation failure..  The two error
messages are garbage, as untested error messages commonly are:

    Parameter 'cache size' expects Failed to allocate cache
    Parameter 'cache size' expects Failed to allocate page cache

Fix them to just

    Failed to allocate cache
    Failed to allocate page cache
