e1000e_write_packet_to_guest() passes the reference of variable ba as a
pointer to an array, and that pointer indirection is just unnecessary;
all functions which uses the passed reference performs no pointer
operation on the pointer and they simply dereference the passed
pointer. Remove the extra pointer indirection.
