 [PATCH v1 08/16] ACPICA: Debugger: drop ACPI_NONSTRING attribute from
 name_seg

From: Ahmed Salem <x0rw3ll@...il.com>

ACPICA commit 4623b3369f3aa1ec5229d461e91c514510a96912

Partially revert commit 70662db73d54 ("ACPICA: Apply ACPI_NONSTRING in
more places") as I've yet again incorrectly applied the ACPI_NONSTRING
attribute where it is not needed.

A warning was initially reported by Collin Funk [1], and further review
by Jiri Slaby [2] highlighted another issue related to the same commit.

Drop the ACPI_NONSTRING attribute to fix the issue.

Fixes: 70662db73d54 ("ACPICA: Apply ACPI_NONSTRING in more places")
