Subject: [PATCH 4.19 11/72] 9p: rename p9_free_req() function
[ Upstream commit 43cbcbee9938b17f77cf34f1bc12d302f456810f ]
In sight of the next patch to add a refcount in p9_req_t, rename
the p9_free_req() function in p9_release_req().
In the next patch the actual kfree will be moved to another function.
