virNetDevOpenvswitchGetVhostuserIfname: Fix off by one error

https://bugzilla.redhat.com/show_bug.cgi?id=1459091

We try to get the last element of the passed path by calling
strrch(path, '/'). However, the pointer that strrchr() returns
points at the slash, We want string that starts right after that.
