[PATCH 7/9] libmultipath: warn only once in scsi_tmo_error_msg()

[Martin Wilck <martin.wilck@suse.com>]

The intention of this code was to warn only once for each unsupported
protocol. But the condition statement is missing.

Fixes: 6ad77db ("libmultipath: Set the scsi timeout parameters by path")
