Make the ata probe* and xpt* routines aprobe* and axpt* respectively.
Often, in traiging core files, one only has a traceback of where a panic occurred. We have probe* and xpt* routines that live in both the scsi and ata layers with identical names. To make one or the other stand out, prefix all the probe and xpt routines in ata with an 'a'. I've left the scsi ones alone since they were there first and are more numerous. I also rejected using #define to do this as being too confusing. I chose this method because the CAM name for the probe device was already 'aprobe'. Normally, this doesn't matter because file scope protects one from interfering with the other. However, due to the indirect nature of CAM's state machine, you don't know if the following traceback is SCSI or ATA: xpt_done probedone xpt_done_process xpt_done_td fork_exit nvme and mmc already have unique names.
