usbnet: smsc95xx: fix rx packet alignment
[ Upstream commit 810eeb1f41a9a272eedc94ca18c072e75678ede4 ]
The smsc95xx driver already takes into account the NET_IP_ALIGN
parameter when setting up the receive packet data, which means
we do not need to worry about aligning the packets in the usbnet
driver.
Adding the EVENT_NO_IP_ALIGN means that the IPv4 header is now
passed to the ip_rcv() routine with the start on an aligned address.
Tested on Raspberry Pi B3.
