Akinobu Mita 4662d8e6ab debugfs: fix error when writing negative value to atomic_t debugfs file 
[ Upstream commit d472cf797c ]

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()"), so we have to use a 64-bit value to write a
negative value for a debugfs file created by debugfs_create_atomic_t().

This restores the previous behaviour by introducing
DEFINE_DEBUGFS_ATTRIBUTE_SIGNED for a signed value.

Fixes: 488dac0c92 ("libfs: fix error cast of negative value in simple_attr_write()")
