md-cache: Process all the cache invalidation flags

Currently, md-cache only processes IATT_UPDATE_FLAGS, UP_XATTR and
UP_XATTR_RM. We also need to process UP_RENAME_FLAGS, UP_FORGET,
UP_PARENT_DENTRY_FLAGS and UP_NLINK_FLAGS. Otherwise the files
unlinked or renamed will not be reflected on other mounts.
