cxl/memdev: Replace ENXIO with EBUSY for inject poison limit reached
The CXL driver provides a debugfs interface offering users the
ability to inject and clear poison to a memdev. Once a user has
injected up to the devices limit further injection requests fail
with ENXIO until a clear poison is issued.
Users may not have device specs in hand or may want to intentionally
hit the limit and then clear. Replace the usual ENXIO return status
with EBUSY so users can recognize this failure.

Documentation/ABI/testing/debugfs-cxl: Fix "Unexpected indentation"
Stephen reported that an htmldocs build hit:
Documentation/ABI/testing/debugfs-cxl:38: ERROR: Unexpected indentation.
It turns out that line was fine but the tool was unhappy about some line
breaks in the table of values to error types.
It turns out that:
make V=1 SPHINXDIRS="admin-guide" htmldocs
...can not be used to get more info about what is behind a documentation
build error. It was only pure luck that reflowing the text resulted in
an error message that seemed a imply a problem later on with line breaks
around the table.

cxl/core: Add CXL EINJ debugfs files
Export CXL helper functions in einj-cxl.c for getting/injecting
available CXL protocol error types to sysfs under kernel/debug/cxl.
The kernel/debug/cxl/einj_types file will print the available CXL
protocol errors in the same format as the available_error_types
file provided by the einj module. The
kernel/debug/cxl/$dport_dev/einj_inject file is functionally the same
as the error_type and error_inject files provided by the EINJ module,
i.e.: writing an error type into $dport_dev/einj_inject will inject
said error type into the CXL dport represented by $dport_dev.
