[ Upstream commit 0c25422d34b4726b2707d5f38560943155a91b80 ]
When scsi_dma_map() fails by returning a sges_left value less than zero,
the amount of logging produced can be extremely high. In a recent end-user
environment, 1200 messages per second were being sent to the log buffer.
This eventually overwhelmed the system and it stalled.
These error messages are not needed. Remove them.
