cifs: check rsp for NULL before dereferencing in SMB2_open
In SMB2_open there are several paths where the SendReceive2
call will return an error before it sets rsp_iov.iov_base
thus leaving iov_base uninitialized.
Thus we need to check rsp before we dereference it in
the call to get_rfc1002_length().
A report of this issue was previously reported in
http://www.spinics.net/lists/linux-cifs/msg12846.html
RH-bugzilla : 1476151
Version 2 :
* Lets properly initialize rsp_iov before we use it.
