block: Make blk_mq_get_sq_hctx() select the proper hardware queue type

Since the introduction of blk_mq_get_hctx_type() the operation type in
the second argument of blk_mq_get_hctx_type() matters. The introduction
of blk_mq_get_hctx_type() caused blk_mq_get_sq_hctx() to select a
hardware queue of type HCTX_TYPE_READ instead of HCTX_TYPE_DEFAULT.
Switch to hardware queue type HCTX_TYPE_DEFAULT since HCTX_TYPE_READ
should only be used for read requests.
