[dpdk-dev] [PATCH 2/2] enic: fix error with uninitialized variable.

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

The variable notify_pa is only initialized inside one branch of
an if statement, triggering a compiler error with clang 3.3 on FreeBSD.

  CC vnic/vnic_dev.o
/usr/home/bruce/dpdk.org/lib/librte_pmd_enic/vnic/vnic_dev.c:777:6: fatal error: variable 'notify_pa'
      is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
        if (!vnic_dev_in_reset(vdev)) {

Fix this issue by adding "= 0" to the variable definition.
