scsi: sd: Fix interpretation of VPD B9h length
commit f92de9d110429e39929a49240d823251c2fe903e upstream.
Fixing the interpretation of the length of the B9h VPD page (Concurrent
Positioning Ranges). Adding 4 is necessary as the first 4 bytes of the page
is the header with page number and length information. Adding 3 was likely
a misinterpretation of the SBC-5 specification which sets all offsets
starting at zero.
This fixes the error in dmesg:
[ 9.014456] sd 1:0:0:0: [sda] Invalid Concurrent Positioning Ranges VPD page
