Revert "drivers:tty:pty: Fix a race causing data loss on close"

This reverts commit 33d4ae98859873ddd49e22e4ca724387548b3d89.

Pierre-Louis writes:

Our SOF/audio CI shows an across-the-board regression when we try v5.12-rc1,
specifically on pause/resume tests with an interactive terminal running 'aplay
-i' commands managed by expect to simulate the user pressing the space bar to
pause/unpause. It turns out the processes are not longer killed and the audio
devices remain busy (see publicly available test results listed below).

git bisect points to commit 33d4ae9885987 ("drivers:tty:pty: Fix a race
causing data loss on close"). Reverting the patch fixes the issue on all test
devices.

Further analysis with Corey Minyard points to a problem where a slave tty will
not get a SIGHUP when the master is closed.

So revert this for now:

tty: protect tty_write from odd low-level tty disciplines

Al root-caused a new warning from syzbot to the ttyprintk tty driver
returning a write count larger than the data the tty layer actually gave
it. Which confused the tty write code mightily, and with the new
iov_iter based code, caused a WARNING in iov_iter_revert().

syzbot correctly bisected the source of the new warning to commit
9bb48c82aced ("tty: implement write_iter"), but the oddity goes back
much further, it just didn't get caught by anything before.

ASoC: Updates for v5.12

Another quiet release in terms of features, though several of the
drivers got quite a bit of work and there were a lot of general changes
resulting from Morimoto-san's ongoing cleanup work.

- As ever, lots of hard work by Morimoto-san cleaning up the code and
making it more consistent.
- Many improvements in the Intel drivers including a wide range of
quirks and bug fixes.
- A KUnit testsuite for the topology code.
- Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured
nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro
- Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers.
