Subject: fsr: fix uninitialized fs usage after timeout
Patch-mainline: Submitted to linux-xfs, 2 Jun 2017
References: bsc#1002699

In the main loop of fsrallfs, we exit when we've hit the timeout but
we increment fs before we get there.  If we're operating on the last
file system in the array, we'll hit an uninitialized fsdesc and
crash in fsrall_cleanup.
