btrfs: combine btrfs_clear_buffer_dirty and clear_extent_buffer_dirty

Browse Source 
btrfs_clear_buffer_dirty just does the test_clear_bit() and then calls
clear_extent_buffer_dirty and does the dirty metadata accounting.
Combine this into clear_extent_buffer_dirty and make the result
btrfs_clear_buffer_dirty.
