[PATCH] fs/xfs: replace strncpy with strscpy

[Pranav Tyagi <pranav.tyagi03@gmail.com>]

Replace the deprecated strncpy() with strscpy() as the destination
buffer should be NUL-terminated and does not require any trailing
NUL-padding. Also, since NUL-termination is guaranteed,
use sizeof(label) in place of XFSLABEL_MAX as the size
parameter.
