This patch marks the function xenvif_count_frag_slots() in netback.c as
static because they are not used outside this file.

Thus, it also removes the following warning in xen-netback/netback.c:
drivers/net/xen-netback/netback.c:218:14: warning: no previous prototype for ‘xenvif_count_frag_slots’ [-Wmissing-prototypes]

This patch doesn't apply cleanly to net-next, please respin.

Thanks.
