firewire: ohci: avoid reallocation of AR buffers
Freeing an AR buffer page just to allocate a new page immediately
afterwards is not only a pointless effort but also dangerous because
the allocation can fail, which would result in an oops later.
Split ar_context_add_page() into two functions so that we can reuse
the old page directly.
