Since commit 488dac0c9237 ("libfs: fix error cast of negative value in
simple_attr_write()"), the EINJ debugfs interface no longer accepts
negative values as input. Attempt to do so will result in EINVAL.
Fixes: 488dac0c9237 ("libfs: fix error cast of negative value in simple_attr_write()")

SGX reserved memory does not appear in the standard address maps.
Add hook to call into the SGX code to check if an address is located
in SGX memory.
There are other challenges in injecting errors into SGX. Update the
documentation with a sequence of operations to inject.
