[ Upstream commit 46393d61a328d7c4e3264252dae891921126c674 ]

Fix the following build/link error by adding a dependency on the CRC32
routines:

ld: drivers/net/usb/lan78xx.o: in function `lan78xx_set_multicast':
lan78xx.c:(.text+0x48cf): undefined reference to `crc32_le'

The actual use of crc32_le() comes indirectly through ether_crc().

Fixes: 55d7de9de6c30 ("Microchip's LAN7800 family USB 2/3 to 10/100/1000 Ethernet device driver")
