[PATCH 0/7] various: 7 minor Coverity fixes

[Peter Maydell]

This patchset fixes seven minor Coverity issues:
 * four minor nits in test code
 * a happens-once memory leak in the af-xdp netdev
 * a harmless wrong-bounds-check in pca9554
 * add a report-write-errors-to-user in mac_nvram

I don't think any of these are worth backporting to stable;
I just picked them as easy fixes that reduce the number of open
Coverity issues we have.

thanks
