[PATCH -next] dmaengine: ti: edma: Fix error return code in edma_probe()

[Wei Yongjun <weiyongjun1@xxxxxxxxxx>]

Fix to return negative error code -ENOMEM from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 2a03c1314506 ("dmaengine: ti: edma: add missed operations")
