xen-netback: fix type mismatch warning
Wiht the latest rework of the xen-netback driver, we get a warning on ARM about the types passed into min(): drivers/net/xen-netback/rx.c: In function 'xenvif_rx_next_chunk': include/linux/kernel.h:739:16: error: comparison of distinct pointer types lacks a cast [-Werror] The reason is that XEN_PAGE_SIZE is not size_t here. There is no actual bug, and we can easily avoid the warning using the min_t() macro instead of min().
