ocfs2: remove redundant ocfs2_alloc_dinode_update_counts() and ocfs2_block_group_set_bits()
ocfs2_alloc_dinode_update_counts() and ocfs2_block_group_set_bits() are already provided in suballoc.c. So, the same functions in move_extents.c are not needed any more. Declare the functions in suballoc.h and remove redundant functions in move_extents.c.
