Subject: parseServers(): Fix uninitialized variable simplify error path
Patch-mainline: Not yet
Git-repo: https://github.com/Unidata/netcdf-c
Git-commit: 06fbbbc78023abca48ae3a69aa409f7f0a4cf3a3
References:

When rtslen == 0 code jumped to 'done' where it checked for rts being
!= NULL. At this point, rts was not yet set.
Fixed code paths eliminating unneeded tests and jumps.
