ocfs2: replace deprecated strcpy in ocfs2_create_xattr_block

Browse source

strcpy() has been deprecated [1] because it performs no bounds checking on
the destination buffer, which can lead to buffer overflows.  Replace it
with the safer strscpy(), and copy directly into '->xb_signature' instead
of using the start of the struct as the destination buffer.
