coer dump from hammer info

[Steve O'Hara-Smith]

	I'm running v2.5.1.376.g8b72b-DEVELOPMENT with hammer version 4
filesystems (upgraded from version 1 original builds). When I run hammer
info I get a coredump as it starts on one of the filesystems (the other two
report OK). The message is:

assertion: z->z_Magic == ZALLOC_SLAB_MAGIC in _slabfree
Abort trap: 6 (core dumped)

	It comes just after reporting on the mountpoints of one filesystem
and just before it would print "Volume identification" for the last
filesystem.

	Core dump attached.

	The filesystem seems to be working fine.
