[Virtio-fs] [PATCH][virtio-fs-dev] virtiofsd: Fix fuse_reply_create() to determine correct length of buffer

[Vivek Goyal]

Hi Dave,

Following patch needs to be applied on virtio-fs-dev branch to make it
work with latest kernel. Otherwise file creation reply returns error.

Thanks
Vivek

Put conditional express in brackets. Otherwise expression being evaluated
becomes (entrysize + sizeof(struct fuse_open_out) + shared) instead and
which obviously results in wrong size calculation.
