Paolo Bonzini 9bd634b2f5 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.
