[PATCH v3 2/3] Rename __scsi_error_from_host_byte() into scsi_result_to_blk_status()

[Bart Van Assche <bart.vanassche@xxxxxxx>]

Since the next patch will modify this function such that it
checks more than just the host byte of the SCSI result, rename
__scsi_error_from_host_byte() into scsi_result_to_blk_status().
This patch does not change any functionality.
