[PATCH v2 1/2] block: Treat all read ops as synchronous

[Jeffy Chen]

The comment for op_is_sync() says "Reads are always treated as
synchronous", but it only checks for REQ_OP_READ.

Use op_is_write() to detect read ops and treat them as synchronous.

Fixes: aebf526b53ae ("block: fold cmd_type into the REQ_OP_ space")
