e1000: fix multicast setting in VF

Description

e1000: fix multicast setting in VF

In function e1000_update_mc_addr_list_vf(), "msgbuf[0]" is used prior
to initialization at "msgbuf[0] |= E1000_VF_SET_MULTICAST_OVERFLOW".
And "msgbuf[0]" is overwritten at "msgbuf[0] = E1000_VF_SET_MULTICAST".

Fix it by moving the second line prior to the first one that mentioned
above.
