 Log Message:
 dounmount/vfs_insmntque: allow vcache_get during VFS_UNMOUNT
 
 we currently have assertions to prevent file systems from
 populating its vnode cache during VFS_UNMOUNT. this commit
 relaxes the assertions a bit to allow vcache_get during
 VFS_UNMOUNT. although VFS_UNMOUNT should still eventually
 drain the vnode cache for the mount, this commit allows it
 to populate its vnode cache temporarily.
 
 this is for zfs, which sometimes need to access znode when
 committing the log. (zfs_get_data)  a forthcoming zfs change
 will depend on this change.
