Subject: [PATCH] initrd: Fix logged Minix/Ext2 block numbers in identify_ramdisk_image()

Both Minix and Ext2 filesystems are located at 'start_block + 1'. Update
the log messages to report the correct block numbers.

Replace printk(KERN_NOTICE) with pr_notice() to avoid checkpatch
warnings.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
