x86/mm: Fix range check in tlbflush debugfs interface
Since the shift count settable there is used for shifting values of type "unsigned long", its value must not match or exceed BITS_PER_LONG (otherwise the shift operations are undefined). Similarly, the value must not be negative (but -1 must be permitted, as that's the value used to distinguish the case of the fine grained flushing being disabled).
