scsi: Change scsi sense buf size to 252
Current buffer size fails the assersion check in like
hw/scsi/scsi-bus.c:1655: assert(req->sense_len <= sizeof(req->sense));
when backend (block/iscsi.c) returns more data then 96.
Exercise the core dump path by booting an Gentoo ISO with scsi-generic
device backed with iscsi (built with libiscsi 1.7.0):
x86_64-softmmu/qemu-system-x86_64 \
-drive file=iscsi://localhost:3260/iqn.foobar/0,if=none,id=drive-disk \
-device virtio-scsi-pci,id=scsi1,bus=pci.0,addr=0x6 \
-device scsi-generic,drive=drive-disk,bus=scsi1.0,id=iscsi-disk \
-boot d \
-cdrom gentoo.iso
qemu-system-x86_64: hw/scsi/scsi-bus.c:1655: scsi_req_complete:
Assertion `req->sense_len <= sizeof(req->sense)' failed.
According to SPC-4, section 4.5.2.1, 252 is the limit of sense data. So
increase the value to fix it.
Also remove duplicated define for the macro.
