filemap: find_get_entries() now updates start offset

Initially, find_get_entries() was being passed in the start offset as a
value.  That left the calculation of the offset to the callers.  This led
to complexity in the callers trying to keep track of the index.

Now find_get_entries() takes in a pointer to the start offset and updates
the value to be directly after the last entry found.  If no entry is
found, the offset is not changed.  This gets rid of multiple hacky
calculations that kept track of the start offset.
