fs/hfsplus/xattr.c: replace strncpy with memcpy
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]
