pnfs/blocklayout: fix last_write_offset incorrectly set to page boundary

Commit 41963c10c47a35185e68cb9049f7a3493c94d2d7 sets the block layout's
last written byte to the offset of the end of the extent rather than the
end of the write which incorrectly updates the inode's size for
partial-page writes.
