cp_payload is set differently [1] when extended node bitmap feature is
enabled. Commit b79c3ba4ea broke fsck on f2fs file systems created on
2+ TB device with extended node bitmap feature enabled.
As the sanity check is for checking overflows, fix this to assume the max
possible cp_payload size under the extended node bitmap.

Keep sanity_check_raw_super flow in fsck.f2fs being consistent w/
sanity_check_raw_super() in f2fs kernel module, otherwise, it outputs
different error information when mounting/fscking the same image which
contains corrupted superblock.

We now use walltime for monthly period check. However the walltime is:
* unstable(timestamp register reset) and settable(modified by user)
* unreasonable(e.g: device power-off for one month, no data changed)
When the walltime changes to the past before one month or the future
after one month, the period check in next fsck will fail to skip or
start a full scan. So, let's use the elapsed_time in checkpoint as
current time for period check.

Cleanly report an error instead of dividing by 0 (causing a floating
point exception) in the following case:
truncate -s 16M img && mkfs.f2fs img
Note that this is a minimal fix; it appears that overly-small images
still cause various integer overflows in f2fs_prepare_super_block().
