Subject: Work around uninitialized warning in cc_kcm.c
X-Git-Tag: krb5-1.15-beta1~299

Work around uninitialized warning in cc_kcm.c

Some versions of clang erroneously detect use of an uninitialized
variable reply_len in kcmio_call() when building on non-Mac platforms.
Initialize it to work around this warning.
