When registering a umem area that is sufficiently large (>1G on an x86), kmalloc cannot be used to allocate one of the internal data structures, as the size requested gets too large. Use kvmalloc instead that falls back on vmalloc if the allocation is too large for kmalloc. Also add accounting for this structure as it is triggered by a user space action (the XDP_UMEM_REG setsockopt) and it is by far the largest structure of kernel allocated memory in xsk.
