[Virtio-fs] [PATCH 1/2] vitriofsd/passthrough_ll: Make fallocate() work

[Xiao Yang]

1) Use correct CONFIG_FALLOCATE macro to check if fallocate() is supported.(i.e configure
   script sets CONFIG_FALLOCATE intead of HAVE_FALLOCATE if fallocate() is supported)
2) Avoid 'Bad file descriptor' error by passing correct fd to fallocate().
