Limit these messages to once every 2 minutes to avoid spamming logs;
with multiple devices the output can be quite significant.
Also, up the default timeout to 30 seconds from 10 seconds.

bcachefs: Use try_cmpxchg() family of functions instead of cmpxchg()2024-07-14T23:00:12ZUros Bizjakubizjak@gmail.com2024-05-23T09:19:26Zurn:sha1:68573b936d3fceda9cd5cce3a577e035d19ad426
Use try_cmpxchg() family of functions instead of
cmpxchg (*ptr, old, new) == old. x86 CMPXCHG instruction returns
success in ZF flag, so this change saves a compare after cmpxchg
(and related move instruction in front of cmpxchg).
Also, try_cmpxchg() implicitly assigns old *ptr value to "old" when
cmpxchg fails. There is no need to re-read the value in the loop.
No functional change intended.

Turn more asserts into proper recoverable error paths.

This fixes a lifetime issue; bch2_nocow_write_unlock() uses
PTR_BUCKET_POS(), which needs the device - but we drop our ref to the
device in bch2_write_endio().

bch2_dev_bkey_exists() is going away; bch2_dev_have_ref() documents that
we're looking up a device without checking if it's present because we
have a reference to it already.
