Kees Cook 4378be89dd ext4: use memtostr_pad() for s_volume_name 
commit be27cd64461c45a6088a91a04eba5cd44e1767ef upstream.

As with the other strings in struct ext4_super_block, s_volume_name is
not NUL terminated. The other strings were marked in commit 072ebb3bffe6
("ext4: add nonstring annotations to ext4.h"). Using strscpy() isn't
the right replacement for strncpy(); it should use memtostr_pad()
instead.

Closes: https://lore.kernel.org/all/00000000000019f4c00619192c05@google.com/
Fixes: 744a56389f73 ("ext4: replace deprecated strncpy with alternatives")
