So you have two XFS filesystems mounted on partitions of this device,
sda2 and sda5.

Yet under /sys/fs/xfs we have sda and sda5. Presumably sda here refers
to sda2.

Six total partitions on the device...

... and according to the kernel, three of them are named sda. :/ This
appears to be the crux of the problem. My understanding is that these
should all have unique names based on the partition. XFS is just going
to reuse that name to create the /sys/fs/xfs/<dev> subdir, so as soon as
you mount another XFS filesystem on top of one of those other similarly
named partitions, the error is going to trigger.

There's nothing obvious enough to me in the boot log to point at a
problem. I've CC'd the linux-block list to see if anybody more familiar
with the block layer might be able to comment on what could be going on
here.
