The asserts makes sure that 'i' doesn't exceed the exepcted value. This to prevent an out of bound access to dbr_bitmap.
The current location of the assert protects the assignment of dbr_bitmap, but not the access to it. Moved the assert to the correct place, to protect both cases. Also, used an existing define for the assert.
