[PATCH v8 2/2] scsi: sd: make sd_revalidate_disk() return void

[Abinash Singh <abinashsinghlalotra@gmail.com>]

The sd_revalidate_disk() function currently returns 0 for
both success and memory allocation failure.Since none of its
callers use the return value, this return code is both unnecessary
and potentially misleading.

Change the return type of sd_revalidate_disk() from int to void
and remove all return value handling. This makes the function
semantics clearer and avoids confusion about unused return codes.
