[ Upstream commit d09845e98a05850a8094ea8fd6dd09a8e6824fff ]

Some kernel-internal ASYNC flags have been superseded by tty-port flags
and should no longer be used by kernel drivers.

Fix the misspelled "__KERNEL__" compile guards which failed their sole
purpose to break out-of-tree drivers that have not yet been updated.

Fixes: 5c0517fefc92 ("tty: core: Undefine ASYNC_* flags superceded by TTY_PORT* flags")
