btrfs-progs: add validation checks for chunk loading

To survive fuzz filesystem images, we need various validation checks to
make btrfsck detect any invalid value inside chunks including those in
 sys_array.

Note that these checks may not be sufficient to cover all corner cases,
we may need to add more later.

This also refractor previous various checks into a helper function so
that we can add more checks into it in the future.
