[PATCH 3/4] multipath: fix clang warning in delegate_to_multipathd

[Martin Wilck <mwilck@suse.com>]

Fixes this warning from clang:

main.c:628:11: warning: variable 'reply' is used uninitialized
whenever 'if' condition is true [-Wsometimes-uninitialized]
...
main.c:609:32: note: initialize the variable 'reply' to silence this warning

Fixes: 506d253b7f89 "multipath: delegate dangerous commands to multipathd"
