Subject: samples: bpf: Drop doubled variable declaration in xdpsock
MIME-Version: 1.0

Git-commit: 32c92c15ad3dca6f7cca8643766ad79fa3ab3d17
References: bsc#1155518

Seems that by accident there is a doubled declaration of global variable
opt_xdp_bind_flags in xdpsock_user.c. The second one is uninitialized so
compiler was simply ignoring it.

To keep things clean, drop the doubled variable.
