net/vmxnet3: fix initialization on FreeBSD

[ upstream commit 40d5676ff1ea43cc2c121fd66d19a29a1c9107bb ]

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: 046f116 ("net/vmxnet3: support MSI-X interrupt")
