get_request and get_request_wait, called by blk_get_request, expects to
get the REQ_SYNC flag in addition to the read/write flag. Moreover, it
uses the REQ_SYNC flag in its algorithm decision making.
However blk_get_request expects to get a Boolean to indicate only
read/write flag and cannot handle the REQ_SYNC flag.
