9pfs: local: lremovexattr: don't follow symlinks

The local_lremovexattr() callback is vulnerable to symlink attacks because
it calls lremovexattr() which follows symbolic links in all path elements
but the rightmost one.

This patch introduces a helper to emulate the non-existing fremovexattrat()
function: it is implemented with /proc/self/fd which provides a trusted
path that can be safely passed to lremovexattr().

local_lremovexattr() is converted to use this helper and opendir_nofollow().

This partly fixes CVE-2016-9602.

Merge remote-tracking branch 'remotes/kvaneesh/tags/for-upstream-signed' into staging

VirtFS update:

Cleanups mostly isolating virtio related details into separate files. This
is done to enable easy addition of Xen transport for VirtFS.

The changes include:

1. Rename a bunch of files and functions to make clear they are generic.
2. disentangle virtio transport code and generic 9pfs code.
3. Some function name clean-up.
