linux 6.2 compat: bio->bi_rw was renamed bio->bi_opf

The bi_rw member of struct bio was renamed to bi_opf in Linux 6.2.
As well, Linux's implementation of bio_set_op_attrs(...) has been
removed.

The HAVE_BIO_BI_OPF macro already appears to be defined, but the
removal of the bio_set_op_attrs(...) implementation makes the build
fall back on the locally-defined implementation, which isn't updated
for the bio->bi_opf change. This commit adds that update.
