kernel: userspace: fix dynamic kernel object alignment
Previous commit 55350a93e9f545f1cfdf3ce10b020c8ce7d74ef7 fixing
address-of-packed-mem warnings uncovered an issue with
the alignment of dynamic kernel objects. On 64-bit platforms,
the alignment is 16 bytes instead of 4/8 bytes (as in pointer,
void *). This changes the function of mapping between kernel
object types and alignments to use the dynamic object struct
as basis for alignment instead of simply using pointers.
This also uncomments the assertion added in the previous commit
55350a93e9f545f1cfdf3ce10b020c8ce7d74ef7 so that we can keep
an eye on the alignment in the future. Note that the assertion
is moved after checking if the incoming kernel object is
dynamically allocated. Static kernel objects are not subjected
to this alignment requirement.
Fixes #41062
