pxe: add a single-tick timeout for PXE stacks which eat transmits

Add a single-tick first-round timeout for PXE stacks which eat the
first transmit under certain circumstances, i.e. gPXE if the ARP table
isn't populated yet.

TODO: encapsulate all send packet/wait for reply code into a common
function.
