Subject: [PATCH] ANDROID: Incremental fs: fix up the build for 5.15-rc1

In commit edb0872f44ec ("block: move the bdi from the request_queue to
the gendisk"), the backing device info moved .h files which breaks the
building of incfs.  Fix this up like was done for fat, just include the
correct .h file.
