x86/entry: Remove _TIF_NOHZ from _TIF_WORK_SYSCALL_ENTRY
Evaluating _TIF_NOHZ to decide whether to use the slow syscall entry path
is not only pointless, it's actually counterproductive:
1) Context tracking code is invoked unconditionally before that flag is
evaluated.
2) If the flag is set the slow path is invoked for nothing due to #1
Remove it.
