ded54580bd bcachefs: Check for duplicate device ptrs in bch2_bkey_ptrs_invalid()
This is something we clearly should be checking for, but weren't -
oops.

7807e14384 bcachefs: Convert various code to printbuf
printbufs know how big the buffer is that was allocated, so we can get
rid of the random PAGE_SIZEs all over the place.

e3728b5003 bcachefs: Initialize padding space after alloc bkey
Packed bkeys are padded up to 64 bit alignment, but the alloc bkey type
was not clearing the pad bytes after the last data byte. This left the
key possibly containing some random garbage at the end.

This problem was found using valgrind.

This patch also changes a path with the inode bkey to clear in the same
way.

Switch to always using bio_add_page(), which merges contiguous pages now
that we have multipage bvecs.

This new helper for the move path avoids creating a new CRC entry when
we already have one that matches the pointer being added.
