Subject: hostlist: fix use of strchr()
Patch-mainline: Not yet
Git-repo: https://github.com/chaos/pdsh
Git-commit: 8ad5f4ff5dcccb87d6723cb36aa8097b27fdae6a
References: 

Problem: Comparison of strchr() result to NUL results in compiler
warnings.

Test strchr() result against NULL instead to avoid the compiler
warnings.
