selftests: xsk: Use correct UMEM size in testapp_invalid_desc
[ Upstream commit 7a2050df244e2c9a4e90882052b7907450ad10ed ]
Avoid UMEM_SIZE macro in testapp_invalid_desc which is incorrect when
the frame size is not XSK_UMEM__DEFAULT_FRAME_SIZE. Also remove the
macro since it's no longer being used.
Fixes: 909f0e28207c ("selftests: xsk: Add tests for 2K frame size")
