Description of problem:
The blkif_get_x86_32_req() and blkif_get_x86_64_req() functions don't
sanity-check the req->nr_segments value.
The functions are part of the 32-on-64 support. They translate block I/O
request structs from 32bit ABI to 64bit ABI and visa versa. They are used in
case 32bit paravirtualized guests (or 32bit hvm guests with pv-on-hvm drivers
installed) are running on a 64bit host.
