udl-kms: handle allocation failure

commit 542bb9788a1f485eb1a2229178f665d8ea166156 upstream.

Allocations larger than PAGE_ALLOC_COSTLY_ORDER are unreliable and they
may fail anytime. This patch fixes the udl kms driver so that when a large
alloactions fails, it tries to do multiple smaller allocations.
