Log Message:	geom: don't write stack garbage in disk labels Most consumers of g_metadata_store were passing in partially unallocated memory, resulting in stack garbage being written to disk labels. Fix them by zeroing the memory first. gvirstor repeated the same mistake, but in the kernel. Also, glabel's label contained a fixed-size string that wasn't initialized to zero.
