kconfig: mconf,nconf: remove unneeded '\0' termination after snprintf()
snprintf() always terminates the destination buffer with '\0' even if the buffer is not long enough. (In this case, the last element of the buffer becomes '\0'.) The explicit termination is unneeded. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
