futex: Remove support for IMMUTABLE
The FH_FLAG_IMMUTABLE flag was meant to avoid the reference counting on
the private hash and so to avoid the performance regression on big
machines.
With the switch to per-CPU counter this is no longer needed. That flag
was never useable on any released kernel.
Remove any support for IMMUTABLE while preserve the flags argument and
enforce it to be zero.
