nilfs2: reject filesystem with unsupported block size
This inserts sanity check that refuses to mount a filesystem with
unsupported block size.
Previously, kernel code of nilfs was looking only limitation of
devices though mkfs.nilfs2 limits the range of block sizes; there was
no check that prevents rec_len overflow with larger block sizes.
With this change, block sizes larger than 64KB or smaller than 1KB
will get rejected explicitly by kernel.
