Pull the SetPageSkipKASanPoison() call in post_alloc_hook() out of the big
if clause for better code readability.  This also allows for more
simplifications in the following patches.

Also turn the kasan_has_integrated_init() check into the proper
kasan_hw_tags_enabled() one.  These checks evaluate to the same value, but
logically skipping kasan poisoning has nothing to do with integrated init.
