scsi-generic: fix buffer overflow on block limits inquiry
Using linux 6.x guest, at boot time, an inquiry on a scsi-generic
device makes qemu crash. This is caused by a buffer overflow when
scsi-generic patches the block limits VPD page.
Do the operations on a temporary on-stack buffer that is guaranteed
to be large enough.
