RDMA/rxe: Use 'bitmap_zalloc()' when applicable
'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.
