==1175==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 216 byte(s) in 3 object(s) allocated from:
#0 0x7f0881809b17 in calloc (/lib64/libasan.so.6+0xaeb17)
#1 0x55b3f110bc78 in send_protocol
/builddir/devel/dlm/dlm_controld/daemon_cpg.c:1872
SUMMARY: AddressSanitizer: 216 byte(s) leaked in 3 allocation(s).
This patch free's the allocated buffer in send_protocol which should be
copied in a different buffer by _send_message() already.
