[dpdk-stable] [PATCH] net/ixgbe: fix queue resource leak

[Qiming Chen]

In the ixgbevf_dev_start function, after initializing the rxtx queue, if
an exception occurs in the subsequent function, the rxtx queue needs to
be released. The patch solves the problem of queue resource leakage.

Fixes: 0eb609239efd ("ixgbe: enable Rx queue interrupts for PF and VF")
