[Qemu-devel] [PATCH -V4 04/26] [virtio-9p] Remove post functions for v9fs_readlink.

["Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>]

From: Venkateswararao Jujjuri (JV) <jvrao@linux.vnet.ibm.com>

In the process of preparation for coroutine threads, remove all post functions
and make the function more readable.
