remove test_state of fs test cases Removes unnecessary test_state structure usage for tracking file descriptors Adds missing close(newfd) call in fs_dup_test.c to prevent file descriptor leaks Simplifies test code by eliminating redundant fd tracking that could lead to incorrect resource management Signed-off-by: wangxingxing <wangxingxing@xiaomi.com>
