mountd: Plug v4root memory leak

Valgrind reports that the memory allocated for eep's e_hostname field
was not being freed.  eep is not visible outside of v4root_create(),
so we don't need to strdup() that string.

Introduced by commit 3b777b0 "exports: NFSv4 pseudoroot support
routines" (Dec 1, 2009).
