Al Viro e472f6814c hostfs: fix memory handling in follow_link() 
[ Upstream commit 7f6c411c9b50cfab41cc798e003eff27608c7016 ]

1) argument should not be freed in any case - the caller already has
it as ->s_fs_info (and uses it a lot afterwards)
2) allocate readlink buffer with kmalloc() - the caller has no way
to tell if it's got that (on absolute symlink) or a result of
kasprintf().  Sure, for SLAB and SLUB kfree() works on results of
kmem_cache_alloc(), but that's not documented anywhere, might change
in the future *and* is already not true for SLOB.

Fixes: 52b209f7b8 ("get rid of hostfs_read_inode()")
