Bug reported by the clang static analyzer.

Description: Dereference of null pointer
File: lvm2.git/daemons/clvmd/clvmd.c
Line: 500

this is false positive - as could be seen from source - few lines above - there
is check of ptr clops - and child_init_signal(status) with non-zero status
parameter runs exit(status) - thus could never reach given condition
