[PATCH 5/5] 9pfs: fix removing non-existent POSIX ACL xattr on macOS host

[Christian Schoenebeck]

When mapped POSIX ACL is used, we are ignoring errors when trying
to remove a POSIX ACL xattr that does not exist. On Linux hosts we
would get ENODATA in such cases, on macOS hosts however we get
ENOATTR instead, so ignore ENOATTR errors as well.

This patch fixes e.g. a command on Linux guest like:

  cp --preserve=mode old new
