some infinite recursion in gen_lsm_tmp_name()

[torbenh]

hi...

i was seeing an infinite recursion in gen_lsm_tmp_name() in trunk.
it only happened with my code, when my __attribute__((restrict)) patch
is applied. 

i dont really know how to reproduce it without it.
but the relevant place doesnt look like its supposed to be a
fallthrough.

see attached patch.
