ocfs2: remove redundant ocfs2_alloc_dinode_update_counts() and ocfs2_block_group_set_...

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.
