Revert "cxgb3: Check and handle the dma mapping errors"

This reverts commit f83331bab149e29fa2c49cf102c0cd8c3f1ce9f9.

As the tests PPC64 (powernv platform) show, IOMMU pages are leaking
when transferring big amount of small packets (<=64 bytes),
"ping -f" and waiting for 15 seconds is the simplest way to confirm the bug.
