Chao Yu 8913f343cd mbcache: fix to detect failure of register_shrinker 
register_shrinker in mb_cache_create may fail due to no memory. This
patch fixes to do the check of return value of register_shrinker and
handle the error case, otherwise mb_cache_create may return with no
error, but losing the inner shrinker.
