IB/hfi1: Allow for non-double word multiple message sizes for user SDMA
The driver pads non-double word multiple message sizes but it doesn't account for this padding when the packet length is calculated. Also, the data length is miscalculated for message sizes less than 4 bytes due to the bit representation in LRH. And there's a check for non-double word multiple message sizes that prevents these messages from being sent. This patch fixes length miscalculations and enables the functionality to send non-double word multiple message sizes.
