fix :cirrus_vga fix OOB read case qemu Segmentation fault
check the validity of parameters in cirrus_bitblt_rop_fwd_transp_xxx
and cirrus_bitblt_rop_fwd_xxx to avoid the OOB read which causes qemu Segmentation fault.
After the fix, we will touch the assert in
cirrus_invalidate_region:
assert(off_cur_end >= off_cur);
