gve: fix -ENOMEM null check on a page allocation
Currently the check to see if a page is allocated is incorrect
and is checking if the pointer page is null, not *page as
intended. Fix this.
Addresses-Coverity: ("Dereference before null check")
Fixes: f5cedc84a30d ("gve: Add transmit and receive support")
