Subject: autofs-5.1.3 - fix unset tsd group name handling
Patch-mainline: Submitted, http://www.spinics.net/lists/autofs/msg01725.html
References: bsc#1062482

Commit 1a64a6bbc5 changed set_tsd_user_vars() to set thread specific
values even if the group name could not be obtained.

But the structure holding the values was not initialized on allocation
so the group field might not be NULL when no group name is available.

Also the macro addition and removal functions didn't properly handle a
macro value of NULL.
