nilfs2: allow btree code to directly call dat operations
The current btree code is written so that btree functions call dat operations via wrapper functions in bmap.c when they allocate, free, or modify virtual block addresses. This abstraction requires additional function calls and causes frequent call of nilfs_bmap_get_dat() function since it is used in the every wrapper function. This removes the wrapper functions and makes them available from btree.c and direct.c, which will increase the opportunity of compiler optimization.
