md/raid10: Fix the data type of an r10_sync_page_io() argument
Fix the following sparse warning:
drivers/md/raid10.c:2647:60: sparse: sparse: incorrect type in argument 5 (different base types) @@ expected restricted blk_opf_t [usertype] opf @@ got int rw @@
This patch does not change any functionality since REQ_OP_READ = READ = 0
and since REQ_OP_WRITE = WRITE = 1.
