mkfs: write the cp page 2 of the checkpoint pack 2 during format

Browse Source 
Currently mkfs followed by fsck will fail with

  [f2fs_crc_valid: 351] CRC validation failed: cal_crc = 4076150800 blk_crc = 0 buff_size = 0x0

This is because the validatie_checkpoint() tries to read and checksum the
cp page 2, and it is invoked on both cp packs.
But format only writes the page 1 of the 2nd checkpoint pack.
