[Qemu-devel] [PATCHv3 3/3] seccomp: general fixes

[Eduardo Otubo]

 1) On qemu-seccomp.c:255, the variable ctx was being used
uninitialized; now it's initialized with NULL and it's being checked at
the end of the function.

 2) Changed the name of the command line option from "enable" to
"sandbox" for a better understanding from user side.
