Fix mounting on FreeBSD

Currently, mounting on FreeBSD fails like this:

 mount_fusefs: ZZZZ<snip> on /mountpoint: No such file or directory

This happens because right after doing argv[a++] = fdnam it's
getting freed before calling execvp().

So move this free() call after execvp(). Also, when asprintf()
fails for fdnam, close device fd before calling exit().
