Subject: [PATCH 1/2] bcachefs: drop unused posix acl handlers

From: Youling Tang <tangyouling@...inos.cn>

Remove struct nop_posix_acl_{access,default} for bcachefs filesystem
that don't depend on the xattr handler in their inode->i_op->listxattr()
method in any way. There's nothing more to do than to simply remove the
handler. It's been effectively unused ever since we introduced the new
posix acl api. See [1] for details.
