ubifs: Fix build errors as symbol undefined
With CONFIG_UBIFS_FS_AUTHENTICATION not set, the compiler can assume that ubifs_node_check_hash() is never true and drops the call to ubifs_bad_hash(). Is CONFIG_CC_OPTIMIZE_FOR_SIZE enabled this optimization does not happen anymore. So When CONFIG_UBIFS_FS and CONFIG_CC_OPTIMIZE_FOR_SIZE is enabled but CONFIG_UBIFS_FS_AUTHENTICATION is not set, the build errors is as followd: ERROR: modpost: "ubifs_bad_hash" [fs/ubifs/ubifs.ko] undefined! Fix it by add no-op ubifs_bad_hash() for the CONFIG_UBIFS_FS_AUTHENTICATION=n case.
