Subject: [PATCH] e1000e: e1000e_enable_tx_pkt_filtering() returns wrong value

e1000e_enable_tx_pkt_filtering() will return a non-zero value if the
driver fails to enable the manageability interface on the host for
any reason; instead it should retun zero to indicate filtering has been
disabled.  Also provide a single exit point for the function.
