scsi: Revert "scsi: sd: Do not repeat the starting disk message"

BugLink: https://bugs.launchpad.net/bugs/2097393

commit da3e19ef0b3de0aa4b25595bdc214c02a04f19b8 upstream.

This reverts commit 7a6bbc2829d4ab592c7e440a6f6f5deb3cd95db4.

The offending commit tried to suppress a double "Starting disk" message for
some drivers, but instead started spamming the log with bogus messages
every five seconds:

	[  311.798956] sd 0:0:0:0: [sda] Starting disk
	[  316.919103] sd 0:0:0:0: [sda] Starting disk
	[  322.040775] sd 0:0:0:0: [sda] Starting disk
	[  327.161140] sd 0:0:0:0: [sda] Starting disk
	[  332.281352] sd 0:0:0:0: [sda] Starting disk
	[  337.401878] sd 0:0:0:0: [sda] Starting disk
	[  342.521527] sd 0:0:0:0: [sda] Starting disk
	[  345.850401] sd 0:0:0:0: [sda] Starting disk
	[  350.967132] sd 0:0:0:0: [sda] Starting disk
	[  356.090454] sd 0:0:0:0: [sda] Starting disk
	...

on machines that do not actually stop the disk on runtime suspend (e.g.
the Qualcomm sc8280xp CRD with UFS).

Let's just revert for now to address the regression.
