scsi: sd: Do not repeat the starting disk message



The SCSI disk message "Starting disk" to signal resuming of a suspended
disk is printed in both sd_resume() and sd_resume_common() which results
in this message being printed twice when resuming from e.g. autosuspend:

$ echo 5000 > /sys/block/sda/device/power/autosuspend_delay_ms
$ echo auto > /sys/block/sda/device/power/control

[ 4962.438293] sd 0:0:0:0: [sda] Synchronizing SCSI cache
[ 4962.501121] sd 0:0:0:0: [sda] Stopping disk

$ echo on > /sys/block/sda/device/power/control

[ 4972.805851] sd 0:0:0:0: [sda] Starting disk
[ 4980.558806] sd 0:0:0:0: [sda] Starting disk

Fix this double print by removing the call to sd_printk() from sd_resume()
and moving the call to sd_printk() in sd_resume_common() earlier in the
function, before the check using sd_do_start_stop().  Doing so, the message
is printed once regardless if sd_resume_common() actually executes
sd_start_stop_device() (i.e. SCSI device case) or not (libsas and libata
managed ATA devices case).
