OPP: debugfs: Fix warning around icc_get_name()



If the kernel isn't built with interconnect support, icc_get_name()
returns NULL and we get following warning:

drivers/opp/debugfs.c: In function 'bw_name_read':
drivers/opp/debugfs.c:43:42: error: '%.62s' directive argument is null [-Werror=format-overflow=]
         i = scnprintf(buf, sizeof(buf), "%.62s\n", icc_get_name(path));

Fix it.
