Akinobu Mita beaf354cdf lib/notifier-error-inject: fix error when writing -errno to debugfs file 
BugLink: https://bugs.launchpad.net/bugs/2003914

[ Upstream commit f883c3edd2c432a2931ec8773c70a570115a50fe ]

The simple attribute files do not accept a negative value since the commit
488dac0c92 ("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.

Link: https://lkml.kernel.org/r/20220919172418.45257-3-akinobu.mita@gmail.com
Fixes: 488dac0c92 ("libfs: fix error cast of negative value in simple_attr_write()")
