commit e57bf9cda9cd ("timerfd: convert to ->read_iter()") breaks booting on debian stable (bookworm, 12.5)

[Bert Karwatzki <spasswolf@web.de>]

Since linux-next-20240411 the booting process on debian stable hangs during the
init messages. I bisected this to commit e57bf9cda9cd, and reverting this commit
in linux-next-20240411 fixes the issue. I'm running debian stable (amd64) on an
MSI Alpha 15 laptop with 64G ram and the following hardware:
