Default scsi_dh_alua: Fix the time inteval for alua rtpg commands

This patch corrects the retry interval for alua rtpg command. Purpose was to retry the commands in seconds.
But that was not happening. Reason is msleep takes argument in milliseconds.

Also added minor text after successful attach.
