xfs: make errortag a per-mountpoint structure
Remove the xfs_etest structure in favor of a per-mountpoint structure. This will give us the flexibility to set as many error injection points as we want, and later enable us to set up sysfs knobs to set the trigger frequency as we wish. This comes at a cost of higher memory use, but unti we hit 1024 injection points (we're at 29) or a lot of mounts this shouldn't be a huge issue. Signed-off-by: Darrick J.
