ACPICA: Switch back to using strncpy() in acpi_ut_safe_strncpy()
ACPICA commit b90d0d65ec97ff8279ad826f4102e0d31c5f662a
I mistakenly replaced strncpy() with memcpy() in commit ebf27765421c
("ACPICA: Replace strncpy() with memcpy()"), not realizing the entire
context behind *why* strncpy() was used.
In this safer implementation of strncpy(), it does not make
sense to use memcpy() only to null-terminate strings passed to
acpi_ut_safe_strncpy() one byte early.
The consequences of doing so are understandably *bad*, as was
evident by the kernel test bot reporting problems [1].
