'index.table' is a bitmap. So use 'bitmap_zalloc()' to simplify code,
improve the semantic and avoid some open-coded arithmetic in allocator
arguments.

Using 'bitmap_zalloc()' also allows the removal of a now useless
'bitmap_zero()'.

Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.

'table_size' is never read, it can be removed.

In fact, the only place that uses something that could be 'table_size' is
'alloc_index()'. In this function, it is re-computed from 'min_index' and
'max_index'.
