parisc: Fix vmap memory leak in ioremap()/iounmap()
commit 513f7f747e1cba81f28a436911fba0b485878ebd upstream.
Sven noticed that calling ioremap() and iounmap() multiple times leads
to a vmap memory leak:
vmap allocation for size 4198400 failed:
use vmalloc=<size> to increase size
It seems we missed calling vunmap() in iounmap().
