Remove priority enforcement from xpt_ation(). It is not good and even not safe in some cases to reduce CCB priority after it was scheduled with high priority. This fixes reproducible deadlock when command sent through the pass interface while ATA XPT recovers from command timeout. Instead of that enforce priority at passioctl(). libcam provides no obvious interface to specify CCB priority and so much (all?) code specifies zero (highest) priority. This change limits pass CCBs priority to NORMAL run level, allowing XPT to complete bus and device recovery after reset before running any payload.
