cache: check errno before invoking cache_release()

if genid changes during cache_init(), check_genid() sets errno to EINTR to force
a re-init of the cache.

cache_release() may inadvertly change errno by calling free().  Indeed free()
may invoke madvise() that changes errno to ENOSYS on system where kernel is
configured without support for this syscall.
