[PATCH cluster 02/21] pmxcfs: correctly log message when directory can't be created

[Shannon Sterz <s.sterz@proxmox.com>]

`mkdir(2)` returns 0 on success and -1 on error. so the check that -1
is returned instead of inverting the return value. since errno would
not be set on success, this either never triggered or acted on stale
errnos only.

    feel free to merge this into the previous commit. mainly sending this
    to separate changes that affect behavior from those that only affect
    formatting
