731241f8d0 kernel: workq: Fix type errors in delayable work handlers
A common pattern here was to take the work item as the subfield of a
containing object. But the contained field is not a k_work, it's a
k_work_delayable.

Things were working only because the work field was first, so the
pointers had the same value. Do things right and fix things to
produce correct code if/when that field ever moves within delayable.

e42c1ed924 net: lwm2m: Fix OMA TLV objlnk encoding
At some point OMA TLV integer encoding was optimised to use the smallest
size possible. This broke the objlnk encoding, which internally used
`put_s32()`, but should always be 4 bytes long. In case the result
32-bit integer would fit into 16 or 8 bytes, it'd get optimized.

Fix this, by creating and writing TLV manually for objlnk instead of
relying on int32 encoder.

d002f8a524 net: lwm2m: Fix attribute sanity check
Validate the respective attribute parameters only if both are provided
at given level. This prevents from comparing for instance unset pmax
value (equal to 0) with some new pmin value sent by the server.

Additionally, fix the sanity check for the `pmax` value set on observer,
after fetching the attribute value at all levels (including the default
value at from the server object). Instead of using wrong max(pmin, pmax)
formula, set the pmax value only if it's a valid one (>= pmin),
otherwise ignore the value and set it to 0. This makes the notification
engine ignore the pmax value set for observation.
