nilfs2: add helper functions to delete blocks from dat file
This adds delete functions for data blocks of metadata files using bitmap
based allocator. nilfs_palloc_delete_entry_block() deletes an entry block
(e.g. block storing dat entries), and nilfs_palloc_delete_bitmap_block()
deletes a bitmap block, respectively.
These helpers are intended to be used in the successive change on
deallocator of block addresses ("nilfs2: free unused dat file blocks
during garbage collection").
