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.
Fixes: 16a26b20d2af ("ubifs: authentication: Add hashes to index nodes")
