fget_unlocked() depends on the freed struct file f_count field being
zero.  The file_zone if no-free, but r284861 added trashing of the
freed memory.  Most visible manifestation of the issue were 'memory
modified after free' panics for the file zone, triggered from
falloc_noinstall().

Add UMA_ZONE_ZINIT flag to turn off trashing.  Mjg noted that it makes
sense to not trash freed memory for any non-free zone, which will be
done later.
