In the new consecutive memory mode of Tx queues allocation, the
needed WQ length is calculated via txq_calc_wqebb_cnt(). This
function is used both in Verbs and Devx modes, but in the Devx queue
creation, the actual length is re-calculated / adjusted for the Devx
API. The queue parameters 'max_inline_data' and 'inlen_send' are used
separately for the length calculation for different modes and the
counts calculated are different as a result.
So passing the mode as a bool input to adjust the calculation in
different modes will solve the mismatch. In the meanwhile, since the
memory and MR are allocated successfully before creating a SQ / CQ.
So the error is not critical and a warning message is enough, the
saved length can be used to create the queue.
