nilfs2: avoid rec_len overflow with 64KB block size
With 64KB blocksize, a directory entry can have size 64KB which does
not fit into 16 bits we have for entry length. So this patch stores
0xffff instead and converts value when read from / written to disk.
Nilfs derives its directory implementation from ext2 filesystem, and
this draws upon the corresponding change on ext2.
