bcachefs: dev_usage updated by new accounting
Reading disk accounting now requires an eytzinger lookup (see:
bch2_accounting_mem_read()), but the per-device counters are used
frequently enough that we'd like to still be able to read them with just
a percpu sum, as in the old code.
This patch special cases the device counters; when we update in-memory
accounting we also update the old style percpu counters if it's a deice
counter update.
