lib/notifier-error-inject: fix error when writing -errno to debugfs file
[ Upstream commit f883c3edd2c432a2931ec8773c70a570115a50fe ]
The simple attribute files do not accept a negative value since the commit
488dac0c9237 ("libfs: fix error cast of negative value in
simple_attr_write()").
This restores the previous behaviour by using newly introduced
DEFINE_SIMPLE_ATTRIBUTE_SIGNED instead of DEFINE_SIMPLE_ATTRIBUTE.
