[PATCH] hfsplus: Replace strncpy with memcpy

[Mathieu Malaterre]

Function strncpy was used to copy a fixed size buffer. Since
NUL-terminating string is not required here, prefer a memcpy function.
The generated code (ppc32) remains the same.

Silence the following warning triggered using W=1:

  fs/hfsplus/xattr.c:410:3: warning: 'strncpy' output truncated before 
terminating nul copying 4 bytes from a string of the same length 
[-Wstringop-truncation]
