bcachefs: Ensure proper write alignment

There was a buggy version of bcachefs-tools which picked misaligned
bucket sizes when formatting, and we're also about to do dynamic block
sizes - which will allow picking logical block size or physical block
size of the device per-write, allowing for better compression ratios at
the cost of slightly worse write performance (i.e. forcing the device to
do RMW or extra buffering).

To account for this, tweak bch2_alloc_sectors_start() to properly align
open_buckets to the blocksize of the write we're about to do.
