 vsock_assign_transport (2)

Hello,

syzbot tried to test the proposed patch but the build/boot failed:

drivers/vhost/vsock.c:659:10: error: call to undeclared function 'kvzmalloc'; ISO C99 and later do not support implicit function declarations [-Werror,-Wimplicit-function-declaration]
drivers/vhost/vsock.c:659:8: error: incompatible integer to pointer conversion assigning to 'struct vhost_vsock *' from 'int' [-Wint-conversion]
