bdi: replace BDI_CAP_NO_{WRITEBACK,ACCT_DIRTY} with a single flag

Browse Source 
Replace the two negative flags that are always used together with a
single positive flag that indicates the writeback capability instead
of two related non-capabilities.  Also remove the pointless wrappers
to just check the flag.
