[PATCH v2] usb: mtu3: Fix NULL pointer dereferences

[Markus Elfring]

> Some pointers are dereferenced before successful checks.

I propose to reconsider and improve also this change description.

* Would a null pointer dereference be possible only with the variables “mep”
  and “mreq” in the implementation of the function “mtu3_gadget_dequeue”?
  (Can it make sense to split the patch according to this detail?)

* How do you think about to convert any more variable initialisations
  to later assignments?

* Will it become helpful to add the tag “Fixes” to the commit message?

Are there chances to take any previous patch review comments better into account
(besides the shown reduction of update steps)?

I suggest to replace the triple dashes before this diffstat by a blank line.
