nvme/fio_plugin: fix zone_append option with multiple files per thread

Browse Source 
Each fio thread can have multiple files that it writes to.
Which is why the per thread spdk_fio_setup() fio callback does
for_each_file() {...}.

One of these files can be e.g. a zoned namespace with append support,
another file could be a zoned namespace on another controller without
append support, and a third file could be a conventional namespace
(which never supports the zone append command).

Right now, we will return a fatal error if a thread has e.g. a zoned
namespace (with append support) together with a conventional namespace.

Instead of returning a fatal error, enable zone append only on the
namespaces that support zone append, and allow namespaces that do
not support zone append to continue as usual (using regular writes).
