tty: Move TIOCSTI toggle variable before kerndoc

Browse Source 
The variable "tty_legacy_tiocsti" should be defined before the kerndoc
for the tiocsti() function. The new variable was breaking the "htmldocs"
build target:

drivers/tty/tty_io.c:2271: warning: cannot understand function prototype: 'bool tty_legacy_tiocsti __read_mostly = IS_ENABLED(CONFIG_LEGACY_TIOCSTI); '

Fixes: 83efeeeb3d ("tty: Allow TIOCSTI to be disabled")
