net: netsec: remove static declaration for netsec_set_tx_de()

Browse Source 
On commit ba2b232108 ("net: netsec: add XDP support") a static
declaration for netsec_set_tx_de() was added to make the diff easier
to read.  Now that the patch is merged let's move the functions around
and get rid of that
