Subject: [PATCH v10 2/3] scsi: sd: Remove redundant printk after kmalloc failure

The SCSI disk driver prints a warning when kmalloc() fails in
sd_revalidate_disk(). This is redundant because the page allocator
already reports failures unless __GFP_NOWARN is used. Keeping the
extra message only adds noise to the kernel log.

Remove the unnecessary sd_printk() call. Control flow is unchanged.
