scsi: BusLogic: Fix missing pr_cont() use

Browse Source 
commit 44d01fc86d952f5a8b8b32bdb4841504d5833d95 upstream.

Update BusLogic driver's messaging system to use pr_cont() for continuation
lines, bringing messy output:

Also diagnostic output such as with the BusLogic=TraceConfiguration
parameter is affected and becomes vertical and therefore hard to read.
This has now been corrected, e.g.:
