cache invalidation error for buffered write
The bug causes corruptions of data read from flash.
The original code performs cache invalidation from "adr" to "adr + len"
in do_write_buffer(). Since len and adr could be updated in the code
before invalidation - it causes improper setting of cache invalidation
regions.
