[SeaBIOS] [PATCH 1/2] scsi: Do not call printf() from scsi_is_ready()

[Kevin O'Connor]

The scsi_is_ready() function may be called from a thread, and it is
not valid to call printf() from a thread.  Convert printf() to
dprintf() to avoid this possibility.

This does mean that cdrom detection (from cdrom_boot() ) may not give
notification of slow cdrom drives to a user.  However, the extra
medium detection time is unlikely to be large anyway.
