Gao Xiang 03c9bf033c erofs: initialized fields can only be observed after bit is set

commit ce063129181312f8781a047a50be439c5859747b upstream.

Currently, although set_bit() & test_bit() pairs are used as a fast-
path for initialized configurations. However, these atomic ops are
actually relaxed forms. Instead, load-acquire & store-release form is
needed to make sure uninitialized fields won't be observed in advance
here (yet no such corresponding bitops so use full barriers instead.)
