scsi: sd: Fix sd_do_mode_sense() buffer length handling

BugLink: https://bugs.launchpad.net/bugs/1953370
commit c749301ebee82eb5e97dec14b6ab31a4aabe37a6 upstream.

For devices that explicitly asked for MODE SENSE(10) use, make sure that
scsi_mode_sense() is called with a buffer of at least 8 bytes so that the
sense header fits.
