isofs: fix build regression

The new isofs_show_options() function fails to build when CONFIG_NLS is disabled: fs/isofs/inode.c: In function 'isofs_show_options': fs/isofs/inode.c:518:44: error: 'CONFIG_NLS_DEFAULT' undeclared (first use in this function) fs/isofs/inode.c:518:44: note: each undeclared identifier is reported only once for each function it appears in This adds a check for CONFIG_JOLIET (which selects NLS), matching the other uses of the iocharset handling in this file. Fixes: 6fecb86 ("isofs: Implement show_options") Signed-off-by: Arnd Bergmann <[email protected]> Signed-off-by: Jan Kara <[email protected]>
