[PATCH] net/vmxnet3: fix use of interrupts on FreeBSD

[Bruce Richardson <bruce.richardson@intel.com>]

DPDK does not support interrupts on FreeBSD, so the vmxnet3 driver
returns error when enabling interrupts as it initializes. We can fix
this by #ifdef'ing out the interrupt calls when building for FreeBSD,
allowing the driver to initialize correctly.

Fixes: 046f11619567 ("net/vmxnet3: support MSI-X interrupt")
