[PATCH 5.15 81/86] scsi: mpt3sas: Remove scsi_dma_map() error messages

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Sreekanth Reddy <sreekanth.reddy@broadcom.com>

commit 0c25422d34b4726b2707d5f38560943155a91b80 upstream.

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.
