Vitaly Wool 2cd8231796 mm/slub: allow to set node and align in k[v]realloc
Reimplement k[v]realloc_node() to be able to set node and alignment should
a user need to do so.  In order to do that while retaining the maximal
backward compatibility, add k[v]realloc_node_align() functions and
redefine the rest of API using these new ones.

While doing that, we also keep the number of _noprof variants to a
minimum, which implies some changes to the existing users of older _noprof
functions, that basically being bcachefs.

With that change we also provide the ability for the Rust part of the
kernel to set node and alignment in its K[v]xxx [re]allocations.
