dm log: fix unitialized bio operation flags
Commit e6047149db ("dm: use bio op accessors") switched DM over to
using bio_set_op_attrs() but didn't take care to initialize
lc->io_req.bi_op_flags in dm-log.c:rw_header(). This caused
rw_header()'s call to dm_io() to make bio->bi_op_flags be uninitialized
in dm-io.c:do_region(), which ultimately resulted in a SCSI BUG() in
sd_init_command().
Also, adjust rw_header() and its callers to use REQ_OP_{READ|WRITE}.
Fixes: e6047149db ("dm: use bio op accessors")
