RDMA/qedr: fix build error without ipv6

Browse source

When CONFIG_IPV6 disabled, we run into a link error:

drivers/infiniband/hw/qedr/qedr_iw_cm.o: In function `qedr_addr6_resolve.isra.3':
qedr_iw_cm.c:(.text+0x4e0): undefined reference to `ip6_route_output_flags'

The ipv6 handling code is obviously not needed here, so this
adds a compile-time check for the Kconfig symbol in all three
places in the code that decide between ipv4 and ipv6.

We don't have to worry about a link error wtih QEDR=y/IPV6=m, as
that configuration is already prohibited by CONFIG_INFINIBAND
depending on "m || IPV6 != m".
