[1/9] block: rename bdrv_reset_dirty_bitmap

We will need functions for set/unset a subregion of BdrvDirtyBitmap, to
fix migration and mirror (accordingly to the following patch "block: fix
spoiling all dirty bitmaps by mirror and migration"). Having the
old function 'bdrv_reset_dirty_bitmap' we'll have to add functions like

bdrv_set_dirty_bitmap_region and bdrv_reset_dirty_bitmap_region

But it is more consistent to have

bdrv_set_dirty_bitmap(BlockDriverState *bs, BdrvDirtyBitmap *bitmap,
                      uint64_t start, uint64_t count)
bdrv_reset_dirty_bitmap(BlockDriverState *bs, BdrvDirtyBitmap *bitmap,
                        uint64_t start, uint64_t count)

for more transparent access to underlaying hbitmap interface. So, here
we rename the considered function to 'bdrv_clear_dirty_bitmap'.

Looks like the same change I made in V10 of my series, so we can drop this.
