parisc: fix find_extend_vma() breakage

The STACK_GROWSUP case of stack expansion was missing a test for 'prev',
which got removed by commit cb8f488c33539f096580e202f5438a809195008f
("mmap.c: deinline a few functions") by mistake.

I found my original email in "sent" folder. The patch in that mail
does NOT remove !prev. That change had beed added by someone else.

Ok, I think we are not much interested in who did it, let's
fix it for good.
