[Intel-wired-lan] [PATCH][next] ixgbevf: ensure xdp_ring resources are free'd on error exit

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The current error handling for failed resource setup for xdp_ring
data is a break out of the loop and returning 0 indicated everying
was OK, when in fact it is not.  Fix this by exiting via the
error exit label err_setup_tx that will clean up the resources
correctly and return and error status.

Fixes: 21092e9ce8b1 ("ixgbevf: Add support for XDP_TX action")
