When handling commands without in-capsule data, we assign the ttag assuming we already have the queue commands array allocated (based on the queue size information in the connect data payload). However if the connect itself did not send the connect data in-capsule we have yet to allocate the queue commands,and we will assign a bogus ttag and suffer a NULL dereference when we receive the corresponding h2cdata pdu. Fix this by checking if we already allocated commands before dereferencing it when handling h2cdata, if we didn't, its for sure a connect and we should use the preallocated connect command.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
