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.
