Date
Fix

ntsync.c:1286:20: warning: call to undeclared function 'gettid';
ISO C99 and later do not support implicit function declarations
1286 | wait_args.owner = gettid();
| ^
ntsync.c:1280:8: warning: unused variable 'index'
1280 | __u32 index, count, i;
| ^~~~~
ntsync.c:1281:6: warning: unused variable 'ret'
1281 | int ret;

by adding the missing include file and removing the unused variables.
