Reduce size of zfs_sb_t: allocate z_hold_mtx separately
zfs_sb_t has grown to the point where using kmem_zalloc() for allocations is triggering the 32k warning threshold. We can't safely convert this entire allocation to use vmem_alloc() instead of kmem_alloc() because the backing_dev_info structure is embedded here. It depends on the bit_waitqueue() function which won't behave properly when given a virtual address. Instead, use vmem_alloc() to allocate the z_hold_mtx array separately.
