[PATCH] ACPI: remove unwarranted use of strncpy

[Jim Meyering]

From: Jim Meyering <meyering@xxxxxxxxxx>

strncpy is best avoided in general.  Here, using strcpy would have
been clearer and semantically equivalent, but we can do better still
by removing it: i.e., use kstrdup in place of kzalloc+strncpy.
