bounce_sg for mqrq_cur and mqrq_pre are proper allocated when initializing the queue and will not be freed before explicitly cleaning the queue. So from the code itself it should be quite confident to remove this check. If that BUG_ON take effects, it is mostly likely the memory is randomly oopsing.
