reiserfs: propagate errors from fill_with_dentries() properly

fill_with_dentries() failed to propagate errors up to
reiserfs_for_each_xattr() properly.  Plumb them through.

Note that reiserfs_for_each_xattr() is only used by
reiserfs_delete_xattrs() and reiserfs_chown_xattrs().  The result of
reiserfs_delete_xattrs() is discarded anyway, the only difference there is
whether a warning is printed to dmesg.  The result of
reiserfs_chown_xattrs() does matter because it can block chowning of the
file to which the xattrs belong; but either way, the resulting state can
have misaligned ownership, so my patch doesn't improve things greatly.

Credit for making me look at this code goes to Al Viro, who pointed out
that the ->actor calling convention is suboptimal and should be changed.
