[PATCH 5/8] nvmet: pci-epf: Remove unnecessary dmaengine_terminate_sync() on each DMA transfer

[Frank Li]

dmaengine_terminate_sync() cancels all pending requests. Calling it for
every DMA transfer is unnecessary and counterproductive. This function is
generally intended for cleanup paths such as module removal, device close,
or unbind operations.

Remove the redundant calls.

This one also fix stress test failure after remove mutex and use new API
dmaengine_prep_slave_sg_config().
