fusefs: fix another semi-infinite loop bug regarding signal handling

fticket_wait_answer would spin if it received an unhandled signal whose
default disposition is to terminate.  The reason is because msleep(9) would
return EINTR even for a masked signal.  One reason is when the thread is
stopped, which happens for example during sigexit().  Fix this bug by
returning immediately if fticket_wait_answer ever gets interrupted a second
time, for any reason.
