x86/itmt: Don't make ITMT enablement depend on debugfs
sched_set_itmt_support() treats debugfs file creation failures as fatal.
When CONFIG_DEBUG_FS is disabled, debugfs stubs return ERR_PTR(-ENODEV),
causing ITMT to be silently disabled.
debugfs is a debug-only facility; its return values should be ignored.
Drop the fatal error handling and enable ITMT unconditionally.
Fixes: d04013a4b21b ("x86/itmt: Move the "sched_itmt_enabled" sysctl to debugfs")
