40574946b8 bcachefs: Better bucket alloc tracepoints 
Tracepoints are garbage, and perf trace even cuts off some of our
fields.

Much nicer to just trace a string, and then we can build nicely
formatted output with printbufs.

6202569777 bcachefs: Move nocow unlock to bch2_write_endio() 
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().

d8585a79be bcachefs: bch2_dev_have_ref() 
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.

b07eb8252f bcachefs: bch2_dev_tryget() 
Most uses of bch2_dev_bkey_exists() are going away, where we assume that
because a key references a device the device most exist - instead, we'll
be explicitly checking if the device exists and getting a reference to
it.

This adds the new helpers.

3a718c0647 bcachefs: On device add, prefer unused slots 
We can't strictly guarantee that no pointers refer to nonexistent
devices - we attempt to, but we need to be safe when the filesystem is
corrupt.

Therefore, change device_add to try to pick a slot that's never been
used, or the slot that's been unused the longest.

ffcbec6076 bcachefs: Kill opts.buckets_nouse 
Now explicitly allocate and free the buckets_nouse bitmap - this is
going to be used for online fsck.

To go RW when we haven't check allocations, we'll do a much slimmed down
version that just initializes the buckets_nouse bitmaps.
