[SMB3] [PATCH] Pass through FSCTL for tools like smbinfo

[ronnie sahlberg]

Note that we pass NULL as indata for SMB2_ioctl_init() so for the time
being we can only use this for those ioctl/fcntl that does not
write data to the server. But there are very many of those.

We can start populating smb2info.c with handlers for this and once it
all looks good we can add support to also write to the server (which
will be easy to do but it would make the patch bigger)
