[PATCH] SCSI core: always store >= 36 bytes of INQUIRY data

This patch (as810c) copies a minimum of 36 bytes of INQUIRY data, even if
the device claims that not all of them are valid.  Often badly behaved
devices put plausible data in the Vendor, Product, and Revision strings but
set the Additional Length byte to a small value.  Using potentially valid
data is certainly better than allocating a short buffer and then reading
beyond the end of it, which is what we do now.
