thermal: intel: Don't set HFI status bit to 1
When CPU doesn't support HFI (Hardware Feedback Interface), don't include
BIT 26 in the mask to prevent clearing. otherwise this results in:
unchecked MSR access error: WRMSR to 0x1b1
(tried to write 0x0000000004000aa8)
at rIP: 0xffffffff8b8559fe (throttle_active_work+0xbe/0x1b0)
Fixes: 6fe1e64b6026 ("thermal: intel: Prevent accidental clearing of HFI status")
