wifi: mt76: dma: fix a regression in adding rx buffers
When adding WED support, mt76_dma_add_buf was accidentally changed to set
the skip_buf0 flag for tx buffers on the wrong queue descriptor entry.
Additionally, there is a rxwi leak when rx buffer allocation fails.
Fix this and make the code more readable by adding a separate function for
adding rx buffers.
