## Summary Fixes stuttering output. The use of the semaphore was causing blocking on non blocking callers. This ensured that the TX DAM would be restated, but when it was switched to trywait in https://github.com/apache/nuttx/commit/8362e3147e8000ea70f622fd02fbcafbcfef1a2b, it left data in the xmit queue unsent. This solution removes the semaphore and restart the DMA on completion if there is more data in the xmit queue to be sent. This prevents dma stop operations called of a completion call back from rentering, the callback and ensures that the call back will see the idle state. ## Impact Fixes issue with TXDMA stuttering output. ## Testing nxp_mr-canhubk3_fmu -- This is an automated message from the Apache Git Service.
