mm/page_alloc: dedupe some memcg uncharging logic

The duplication makes it seem like some work is required before uncharging
in the !PageHWPoison case.  But it isn't, so we can simplify the code a
little.

Note the PageMemcgKmem check is redundant, but I've left it in as it
avoids an unnecessary function call.
