Now that the kernel no longer has pcommit support, remove the ndctl
test.

A recent kernel fix addressed cases where a live setting change
mismatches with the current contents of the info block. Rather than
silently overwrite the new settings with the info block contents the
kernel now invalidates the info block if the uuid changes, but otherwise
warns if a setting is mismatched.

For example:
{
"dev":"namespace0.0",
"mode":"dax",
"size":8453619712,
"uuid":"277919a1-ba36-4f41-89b5-c9eebb9b7e33",
"daxdevs":[
{
"chardev":"dax0.0",
"size":8589934592
}
]
}
Note that "daxdevs" is an array because there may be more than one
per-namespace in the future.

Subject: [PATCH] ndctl: bash completion updates for the --namespace= filter
Add completion for the new --namespace= filter.
This will list idle namespaces for completion. It could possibly be made
smarter by checking if a '--idle' or '-i' has been specified on the
command line so far, but maybe that's a bit confusing for the user?
For now, enable the simpler path of listing everything for completion.

Otherwise ndctl may use an old version of ndctl-libs. The expectation
is that installing an updated ndctl also includes all the capabilities
of an updated libndctl.

The kernel is converting nfit_test resources to vmalloc() instead of
DMA_CMA. DMA_CMA collides with other common options enabled in
distribution kernels which makes nfit_test unusable without intrusive
kernel configuration changes. The vmalloc conversion precludes higher
than PAGE_SIZE alignment configurations for pfn + dax devices. Instead,
move these tests to run against an memmap=ss!nn range.

check_namespaces() used to do some i/o testing, but that's long since
been replaced. Clean up some straggling statements.
