gve: fix unused variable/label warnings
On unusual page sizes, we get harmless warnings:
drivers/net/ethernet/google/gve/gve_rx.c:283:6: error: unused variable 'pagecount' [-Werror,-Wunused-variable]
drivers/net/ethernet/google/gve/gve_rx.c:336:1: error: unused label 'have_skb' [-Werror,-Wunused-label]
Change the preprocessor #if to regular if() to avoid this.
Fixes: f5cedc84a30d ("gve: Add transmit and receive support")
