fscrypt_decrypt_pagecache_blocks() can fail, because it uses skcipher_request_alloc(), which uses kmalloc(), which can fail; and also because it calls crypto_skcipher_decrypt(), which can fail depending on the driver that actually implements the crypto. Therefore it's not appropriate to WARN on decryption error in __ext4_block_zero_page_range(). Remove the WARN and just handle the error instead.
